Question

1. the density of copper is 8.96 g/ml. the volume of 12 mg of copper is ____. (3pts) 1.3 ml 0.0013 ml 13 ml 0.013 ml

Explanation:

Step1: Convert mass to grams

$12\ \text{mg} = 12 \times 10^{-3}\ \text{g} = 0.012\ \text{g}$

Step2: Use density formula for volume

Density formula: $
ho = \frac{m}{V}$, rearranged to $V = \frac{m}{
ho}$
Substitute values: $V = \frac{0.012\ \text{g}}{8.96\ \text{g/mL}}$

Step3: Calculate the volume

$V \approx 0.00134\ \text{mL} \approx 0.0013\ \text{mL}$

Answer:

0.0013 mL
