*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
