1. How many molecules are in 43.2 g of sulfur dioxide?
2. If I had 1.23x1024 molecules of hydrochloric acid, how many grams of acid would I have?
1 Molar mass: 64.066 g/mol for sulfur dioxide
43.2/64.066 x 6.022 x 1023 molecules
2 Molar mass: 36.458 g/mol for HCl
( 1.23 x 1024 ) / (6.022 x 1023 ) * 36.458 = ............ gm HCl
