How many silver atoms are there in 3.78 g of silver?

This problem 51 from chapter measurement is based on moral concept. Here we have to find the number off silver atoms present in 3.78 Graham off silver that is, mask off. Silver is given us 3.78 g. We know that atomic mass off silver is one note eight Graham Permal No, we have to find out there. Number off silver atoms. For this we will use the formula for calculating the number of world's first number off moles. Off silver is equals to given weight off silver upon atomic mass of silver that is 3.78 divided by one note eight and the number of moles of silver comes out. Toby Point Not 35 moles. Now we know that one more off silver will have 6.22 and 2 10 to the power 23 silver items. So find Lord 35 mol off silver will have there is 2.11 into 10 to the power 22 atoms. Now we have 3.78 g off silver will contain 2.11 and 2 10 days to power 22 atoms off silver

To answer this question, we have to convert the mass off a silver to the most lives over on DDE on Don't calculate how many atoms seen this among two observer. So the number off most equals to the mess divided by the molar mess. So the more massive silver is one point is well, seven times eight to so the number off most equals two. They must divided by 101 107 times 8 86 equals to 0.35 more Andi. In each mall off atom, there is 6.22 times 10 to the power of 23 atoms. And then we can calculate we can calculate the number of atoms like by using these two. By using this to we're time these two together we would know there is two point while want hamster into the power of 22 items

In today of the guns over. Question number 18 Which talks about how many moles of gold easing a serum if you have a certain moment. So so you have three points were fine. Turns 10 to the 24 Adams. That's gold. This you your name for everyone? More help. I'm a card number 62 times two, 2 20. So then your items from so you knew with but you won't need.

To start this problem. Identify your variables. We know that we're starting with 11 grams of silicone. We also know that silicones Mueller Mass given to us by the periodic table is 28 0.9 grams per mole. We also know that all the God rose number is 6.2 to times 10 to the 20 third Adams. Permal. So what do we need? We need to figure out first how many moles are present and then second, how maney Adams were looking for. Okay, let's start with moles. I'm gonna number this part one so you can follow the math. Okay, We're starting with 11 grams of silicone to get two moles. We could use the Moeller Mass to cancel out this unit of grams and just get moles. To do this, we would divide 11 grams by the molar mass to get an answer of 0.392 moles. That is your answer to part one, but we still need to figure out part two. So right here, we're going to start with part two, and to get to Adams, we can use all the God Rose number to once again cancel out the unit of moles and be left with Adams. To do this, you would multiply by off gardeners number 6.2 to times 10 to the 23rd Adams per mole. Moles cancel and you're left with Adams. And then I plugged this these two numbers into my calculator. Do you get a final answer of to point three? Six times 10 to the 23rd Adams. Okay, to make this a little bit easier to read, I'm going to square in my answer for number one in purple, which is the number of moles. And then for part two, I'm going to put that in orange, and those are the two final answers you should get.
