Question

1. Calculate the density of a substance with a mass of 5.788 g in a volume of 4.22 mL

Answer 1

Answer:

1.37g/ml

Step-by-step explanation:

What is density?

Density (ρ) is simply the mass (m) per given volume (V) of a substance

The formula is therefore:

ρ = m/V

Just as speed is distance covered per a given period of time;

We have a mass and we have a volume, all we need to do is plug into the formula:

ρ = 5.788/(4.22)

ρ = 1.37156398104 → 1.37 (rounded to 3 significant figures)

Finding the units is easy, the mass is in g and the volume is in ml and the mass is divided by volume so the units are: g/ml
