A particular 3.0 L solution contains 2.5 mmol (millimoles) of a substance. What is the concentration of this solution in number
bearhunter [10]

Answer: 0.83mol/m3

1L = 0.001m3

Therefore 3L = 3x0.001 = 0.003m3

0.003m3 contains 0.0025mol

Therefore, 1m3 will contain = 0.0025/0.003 = 0.83mol

The concentration in mol/m3 is 0.83mol/m3
