Question

whats the mass of an object with a density of 19 g/ml and a volume of 3 ml?
answer options:
select one of four
0.15 g
57 g
5.7 g
6.3 g

Explanation:

Step1: Recall density formula

The formula for density is $
ho = \frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume. We need to solve for $m$, so rearrange the formula to $m =
ho \times V$.

Step2: Substitute values

Given $
ho = 19\ \text{g/mL}$ and $V = 3\ \text{mL}$, substitute into the formula: $m = 19\ \text{g/mL} \times 3\ \text{mL}$.

Step3: Calculate the product

$19\times3 = 57$, so $m = 57\ \text{g}$.

Answer:

57 g (corresponding to the option with "57 g")
