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

Any mixture that looks the same through the substance is homogenous. The different parts are unable to be visibly seen. (Any periodic element is homogenous)
Any mixture that can be easily determined a mix and cannot be evenly separated or dispersed is heterogenous.
