How do I solve these?

1) The density of benzene is 0.879 g / mL. Calculate the mass in grams of 4.25 qt of benzene. (1 qt = 2 pt, 1 pt = 473 mL)

2) What's the density of a material that has 20kg of mass and 2m3 of volume. Solve kg to g.

How do I solve these?

1)

The density of benzene is 0.879 g / mL.

Calculate the mass in grams of 4.25 qt of benzene.

(1 qt = 2 pt, 1 pt = 473 mL)

$$\begin{array}{|rcll|} \hline && 0.879\dfrac{\text{g}}{\text{mL}} \times \dfrac{473\text{ mL}}{1\text{ pt}} \times \dfrac{2\text{ pt}}{1\text{ qt}} \times 4.25\ \text{qt} \\ &=& 0.879\times 473 \times 2 \times 4.25\ \text{g} \\ &=& \mathbf{3534.0195\ \text{g}} \\ \hline \end{array}$$
