Question

what is the mass of 531 ml of a liquid that has a density of 0.800 g/ml?
664 g
0.425 g
0.0015 g
425 g

Explanation:

Step1: Recall the density formula

Density formula is \(
ho=\frac{m}{V}\), where \(
ho\) is density, \(m\) is mass and \(V\) is volume. We need to solve for \(m\), so \(m =
ho\times V\).

Step2: Substitute the given values

Given \(V = 531\space mL\) and \(
ho=0.800\space g/mL\). Then \(m=(0.800\space g/mL)\times(531\space mL)\).

Step3: Calculate the mass

\(m = 0.800\times531=424.8\approx425\space g\)

Answer:

425 g
