Calculate the volume of 2.65 moles of CO2 gas at STP.
Harman [31]

Answer:

The volume is 59, 3 liters. See the explanation below, please

Explanation:

STP conditions (standard) correspond to 273K of temperature and 1 atm of pressure. These values are used and the volume is calculated, according to the formula:

PV = nRT

1 atm x V= 2, 65 moles x 0, 082 l atm/K mol x 272 K

V= 2, 65 moles x 0, 082 l atm/K mol x 272 K/1 atm = 59, 3 liters

If you have 3.01 E24 molecules of CO, how many moles of CO do you have?
MA_775_DIABLO [31]

Answer: 5moles

Explanation:

1mole of a substance contains 6.02x10^23 molecules.

Then, 1mole of CO also contains 6.02x10^23 molecules.

If 1 mole of CO2 contains 6.02x10^23 molecules, it means Xmol of CO contains 3.01 E24 ie 3.01x10^24 molecules

Xmol of CO = 3.01x10^24 / 6.02x10^23

Xmol = 5moles
