# Physical Science- Math skills

Rachel is asked to calculate the density of a liquid. She correctly measures the mass of the liquid to be 14 grams, but she incorrectly measures the volume of the liquid to be 10 mL.
The actual volume of the liquid is 9 mL.

If Rachel uses the following equation to calculate the density of the liquid
14 g รท 10 mL = 1.4 g/mL

how will Rachel's incorrect measurement of volume affect her density calculation?

1. Rachel obtains 14/10 = 1.4 g/mL whereas she should obtain
14/9 = 1.555 which I would round to 1.6 g/mL if she had measured the volume correctly.
