Show work for the following examples

1) What is the mass of 1 mole of H2O2 (Hydrogen peroxide)?

2) Calculate the mass of 1 mole of NaNO3 (Sodium nitrate)?

3) How many atoms are in 8.0 moles of Argon?

8.0 mol Ar ( \ ) = atoms of Ar

4) How many moles of Kr are in 132g of Krypton?

132 g Kr
( \ ) = moles of Kr

Next are 2 step equations

5)How many atoms are in 96.4 g of Si?

94.6 g Si ( \ ) ( \ ) = atoms of Silicon

6) What is the mass in grams of 4.8 10^24 atoms of Magnesium?

I got most of this one but I'm not sure what the next step is :

4.8
10^24 atoms of Mg (1\(6.022 10^23)) * (24\1) = 191 g Mg
