Question

What is the concentration of a 22 grams of carbon dioxide occupying 0.5 m^3 volume?

(a) 1 mole/m^3

(b) 2 mole/m^3

(c) 11 mole/m^3

(d) 22 mole/m^3

This question was addressed to me in final exam.

I need to ask this question from Concentration topic in portion Moles, Density & Concentration of Basic Chemical Engineering

Answer 1

The correct answer is (a) 1 mole/m^3

To explain I would say: Moles of carbon dioxide = 22/44 = 0.5, => concentration = 0.5/0.5 = 1 mole/m^3.
