Answer 1

what is the mass, in grams, of 150mL of liquid with a density of 1.4g/mL ?

The mass density or density of a material is its mass per unit volume. Using this definition mass can be calculated as follows:

$$\rho = \frac {m}{V} \Rightarrow m = \rho * V;$$ $$m = 1.4 \frac {g}{m L} * 150 \frac {m L}{1} = 210 g$$

Answer: m=210g
