Question

I am asked to make a solution of 100 ml with H2SO4 as the solute, how exactly can I compute for the molarity when it is lacking the mass of the solute?

Answer 1

Explanation:

Rearranging the equation for concentration allows the mass of solute to be calculated:

mass of solute in g = concentration in g/dm 3 × volume in dm 3

A solution of sodium chloride has a concentration of 10 g/dm 3. ...

mass of solute in g = concentration in g/dm 3 × volume in dm 3

= 10 g/dm 3 × 2 dm 3
