An 8.129 g sample of $\mathrm{MgSO}_{4} \cdot x \mathrm{H}_{2} \mathrm{O}$ is heated until all the water of hydration is driven off. The resulting anhydrous compound, $\mathrm{MgSO}_{4},$ weighs $3.967 \mathrm{g} .$ What is the formula of the hydrate?

Okay, So we're gonna take our hydrate and we're going to heat it up And we start with 5.4959 g of our hydrate. And we're left with 2.583 g of the anhydrous salt. So that means if I subtract those, I should be able to get the mass of the water. Yes, I'm just gonna go ahead and subtract those And I'll see that I get to eight 76 g of H 20. So first let's go ahead and find that value for X. The number of water molecules attached. Yeah, I'll start with my 2583 g of our and hydro salt and my 2876 g of water. So these are mole ratios. So let's go ahead and change grams to moles in each case For this one. This is going to be 258 0.22 Which will give us .0100 moles. And for the water one mall Is 18.2 g. So that will give us 1596 moles. And to get the simplest ratio will divide them both by the smallest number. Well that's gonna be one And that's going to be 16. So X is 16. It would be 16 water molecules attached to each of those anhydrous salts to give us our hydrate. And then finally, we'll find the percentage of water. That's just our massive water, which is 2.876g divided by our total massive hydrate, right percentages, part over whole. And we multiply by 100 and we'll get our percentage Which is 52 .68% Water.

Good day. And this question we will solve for the value of waters of hydration. X. So first we need to find the mass of H 2 0. or mass of water. Castle rotary is equal to the mass of Hydrated compound. CUCL two XH 2 0 miners. The mass of anhydrous compound, Which is the CUCL two. So they must given in the Problem is 3.41 grabs My nurse. The anhydrous g is 2.69 g. Therefore The mass of H 20 is equal to .72 rounds. Now we need to solve the most of water and the anhydrous compound. So all age too old is equal. Duma's over Malema's where Mueller was is the sum of all the atomic one says of elements present in the compound. So mass of water is .72g Divided by 18.02 g per mole. And this will give us .03996 mol. Next more CUCL two is equal to much of a smaller must, Where most of the UCL two is 2.69 g And Mueller must of 134.446 g per mole. This will give us why is Hero 2001 mullen in finding the value of X. X. Is the ratio between mall of water and more of an hydro's compound. So this is All of water is for a 03996 mold divided by Why is 0-001 fallen. Therefore X is equal to do and a re hydrated compound is named US CUCL two two H 20. Thank you.

From the giving caution. We have general formula off Epsom soul that is M G s 04 multiplied by X amount off edge tool mass off Epson sold along with water Hydration is 4.93 grams mass after dehydration is 2.41 round. So the amount off water present will be two point to five gram, hence the number off moles off water can be calculated. Witches 0.14 months by the number off. Mold off salt after dehydration turns out to be 0.20 Moles the number off morals. We can write this Udo formula from the above element which is represented as shown. We divide the simplest value toe obtain the ball in teacher value which gives MGs 041 to really show off water seven. Hence the empirical formula is MGs 04 Indo seven edge dual

Is there a problem? 1 34 of chapter three in chemistry Milica approach. Ah, hydrate. You know Hydra of copper tube chloride with formula. See, You see, l two of that X H 20 It has the water, the water and 343.41 gram sample Example was of hydrates given off by a sample Has a the many samples of mass of 2.69 grams. So that means that C c you seal to that has 2.69 grams Because the water's gone, that's the only thing is love. Find number of waters of the high tree borders of hydration in the hydrate. So this pretty sure forward to find number. I kind of mastered the water We take 3 40 3.41 minus 2.69 And that gives us That's the mass of our water. Nine. This is 0.72 grams names of water and then we're going to find the empirical form us. Now let's take a 2.69 We're gonna Cooper convert them both into moles. So one more over 18 grams and then one more. There There's one copper into chlorine. So copper has a molecular weight of 63.5 by post two time 35.5 that's 134.5 grams. That's gonna equal 0.0 for moans, and this one's gonna equal 0.2 moles. So now we divide both by 0.2 there's gonna equal to and there's gonna equal one. So that means that we have to water molecules forever. You see, You see, L too. So that means that X is equal to two. And our formula is See you seal to to H 20 and we're done.
