Answer:
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
