What is the volume of 34 grams of carbon dioxide at stp

The volume is 17, 3 L

Explanation:

We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273 K of temperature. We convert grams into moles of CO2. We calculate the weight of 1 mol of CO2.

Weight 1 mol C02 = weight C + (weight 0) x2 = 12g + 16g x2 = 44 g/mol

44 g - --1 mol

34g---x = (34g x 1 mol) / 44g = 0,77 mol

PV=nRT V = (nRT) / P

V = (0,77mol x 0,082 latm/K mol x 273K) / 1 atm = 17, 3 liters
