Question

1. calculate the mass of a liquid with a density of 25 g/ml and a volume of 15 ml. given: work answer:

Explanation:

Step1: Recall the 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 mass, so we rearrange the formula to $m=
ho\times V$.

Step2: Identify given values

We are given $
ho = 2.5\space g/mL$ and $V = 15\space mL$.

Step3: Substitute values into the formula

Substitute $
ho = 2.5\space g/mL$ and $V = 15\space mL$ into $m=
ho\times V$. So $m = 2.5\space g/mL\times15\space mL$.

Step4: Calculate the mass

$2.5\times15 = 37.5$. So the mass $m = 37.5\space g$.

Answer:

The mass of the liquid is $37.5\space g$.
