What is the mass of 0.122 mol $\mathrm{Mg} \mathrm{CO}_{3} ?$

In this situation we have to find the mass of one semi cube of oxygen. At STP the first of all, I am writing the given data for distribution. We have given the condition that it is STP and we have given volume that is busy equals to one semi cube and We know that stupid temperature is 0°C or I can say to 73 can win. Now using ideal situation, we can say that PVS equals to an arty here and is the number of moles. So this is B B by RT at STP pressure is one atmospheric pressure. So now put all the data in this equation. So this is one into one into the system to the power -3 Upon this is 0.082 into this is to 73. After solving this, we get this is 10 to the -3 upon 22.4. Now we know that mars is given by that is marches equals two. Number of moles into molecular weight number of moles we had calculated that is turning into this is molecular weight, that is capital. Um, and this is mars is, this is small and now put the value of and so this is 10 to the Power Monastery, sorry, 10 to the power -3 upon this is 22.4 and Mas is 32 grounds. So after holding this, we get the value of mosques. That is 1.4 to 8 to 10 to the Power Monastery Graham Or I can say this is 1.4-8 mg. So this is the mask of one semi cuba of oxygen at escapee. And this is our answer for this given fusion. Thank you.

In this problem were asked to calculate the average mass in grams of one atom of oxygen. We can start with our one atom of oxygen and divide by all the gardeners number because we know that there is this amount of Adams in every single one mole off oxygen. Since we're now in units of moles of oxygen, we can multiply by the molar mass of oxygen to go from moules to grants. And this gives us our weight of one atom of oxygen which is equal to 2.66 tens, 10 to the negative 23 grants.

First time writing the reaction here, I can write to KN 03. So I did give UK and or two Solid plus or two gas here and is equal to tv by RT. That is the number of modes which is equal to one multiplication, 21.1 liter by 0.8 to one little 80. Um Permal per Calvin multiplication 273 Kelvin which is equal 2.9 or one moon or two. Now mars of k n 03 G n 03 mars here is equal to 0.9.1 molo to multiplication to more cayenne or three by one more or two multiplication, 101.1 g K n 03 by one more cayenne or three which is equal to 1 90 g P & 03 at the mosque.

Trey hopping on over. Question number five, Which trucks? A bow. A more Adams oven element. So you have just this one mall Adams of and Element to find that you would need to know the mother match of the
