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

Verified Answer :

1) (1.00mol H2O2)(34.02g/mol H2O2) = 34.02g H2O2

2) (1.00mol NaNO3)(84.99g/mol NaNO3) = 84.99g NaNO3

3) (8.00mol Ar)(6.02x10²³) = 4.82x10²⁴ atoms

4) (132g Kr) / (83.79g/mol Kr) = 1.58mol Kr

5) (96.4g Si)/(28.09 g/mol Si) = 3.43mol Si
(3.43mol Si)(6.02x10²³) = 2.07x10²⁴ atoms Si

6) You did this one correctly :)
