Question

1. if the mass of a rock is 23.8 g and the volume of that rock is 4.51 ml, what is the density of that rock? (hint: density (g/ml) = mass (g)/volume (ml))

a) 0.189 g/ml
b) 19.29 g/ml
c) 28.31 g/ml
d) 5.28 g/ml

Explanation:

Step1: Recall density formula

Density $(\text{g/mL}) = \frac{\text{mass (g)}}{\text{volume (mL)}}$

Step2: Substitute values

Mass = $23.8$ g, Volume = $4.51$ mL. So Density = $\frac{23.8}{4.51}$

Step3: Calculate the division

$\frac{23.8}{4.51} \approx 5.28$ g/mL

Answer:

D. 5.28 g/mL
