Question

Calculate the volume of a carbon monoxide when 22 grams of CO(g) exerts a pressure of 99.5 Kpa at 50 C.

The topic is Chemistry and is Ideal gas laws, please help

Answer 1

21.32 L

Explanation:

First, convert grams to moles using molar mass. C has a mass of 12 and O has a mass of 16. CO2 will therefore have a mass of 28 g/mol. Divide 22 by 28 to get about 0.79 moles. Convert C to Kelvin by adding 273; getting 323K. Then use the ideal gas law (PV=nRT) to solve for V (V=nRT/P). This gets you 21.32 L, hope this helps!
