2. A student measures the mass of a substance as 1.7132 kg and its volume 1 point as 0.65 L. What is the density of the substance in g/mL? Round your answer
to the correct number of significant figures.

The density of the substance is  2.6357 x 10⁶ g/mL

Explanation:

Given;

mass of the substance, m = 1.7132 kg

volume of the substance, v = 0.65 L

the density of the substance in g/mL will be calculated by applying the following formula;

Density = mass / volume

The mass of the substance in grams (g) = 1.7132 kg x 1000 g  = 1713.2 g

The volume of the substance in mL = 0.65 L  x 10⁻³ mL =  0.65 x 10⁻³ mL

Density of the substance = mass / volume

Density of the substance = (1713.2 g) / (0.65 x 10⁻³ mL)

Density of the substance = 2635692.3 g/mL

Therefore, the density of the substance is  2.6357 x 10⁶ g/mL

consider the reaction below.
