The density of a solid gold at room temperature is 19.3 g/mL. Given a 45-mg sample of gold, what is the volume in mL?

Volume is 0.00233mL

Explanation:

Hello,

The density of a substance is the mass per unit volume of that substance.

Density = mass / volume

To solve this question, we need to get our data first.

Data;

Density = 19.3g/mL

Mass = 45mg = 0.045g

Volume = ?

Density = mass / volume

Density (ρ) = mass (m) / volume (v)

ρ = m / v

v = m / ρ

v = 0.045 / 19.3

v = 0.00233mL

The volume of the substance is 0.00233mL

so what is the problem with your lab report and whats the subject of the lab report? i will you
