Question

1. a certain liquid sample has a volume of 14.7 ml and a mass of 22.8 grams. calculate its density. a 1.55 g/ml b 2.25 g/ml c 3.45 g/ml d 4.15 g/ml

Explanation:

Step1: Recall density formula

Density ($
ho$) is defined as mass ($m$) divided by volume ($V$), so the formula is $
ho = \frac{m}{V}$.

Step2: Identify given values

We are given the volume $V = 14.7\space mL$ and the mass $m = 22.8\space g$ (assuming the mass value is 22.8 g, as it's a common mass unit here).

Step3: Calculate density

Substitute the values into the formula: $
ho=\frac{22.8\space g}{14.7\space mL}$.
Calculating this division: $\frac{22.8}{14.7}\approx1.55\space g/mL$ (matching option a).

Answer:

a. 1.55 g/mL
