Answer
$$d = 1.48 \space g/mL $$
Work Step by Step
$$m = 22.54 \space kg \times \frac{1000 \space g}{1 \space kg} = 22540 \space g$$ $$V = 15.2 \space L \times \frac{1000 \space mL}{1 \space L} = 15200 \space mL$$
$$d = \frac{m}{V} = \frac{22540 \space g}{15200 \space mL} \approx 1.48 \space g/mL $$
