3. How many moles of carbon dioxide gas, CO2, are there in 2.8 L of this gas<br> at STP?
kenny6666 [7]

Answer:

The answer is: 0,13 moles of CO2

Explanation:

We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273K of temperature:

PV=nRT n=PV/RT

n=1 atm x 2,8 L/ 0,082 l atm/K mol x 273K

n= 0,125078173 mol
