Q11 of 55 Page 1

If the density of a solution is 3.12 g mL–1, the mass of 1.5 mL solution in significant figures is _______.

Density is given by the formula

Density = mass/volume


By substituting the values, we get


3.12 = mass/1.5


Mass = 4.68g. Since the solution is asked in significant figures, the solution should be rounded up to two significant figures, i.e. 4.7g. The correct answer is (i).
