Answer:
Density of the sample in Kg/L is 8kg/L.
Explanation:
we know that density of a substance can be calculated if we know the mass and volume of the substance.
In this case mass, (M) = 320 g
and Volume (V) = 40 ml
we know that density (ρ) = [tex]\frac{Mass}{Volume}[/tex] = [tex]\frac{320}{40}[/tex] g/ml = 8 g/ml
We also know that 1kg = 1000g and 1litre = 1000ml
so to convert g/ml to kg/l
ρ = (8 × [tex]\frac{1000}{1000} \fra[/tex] )Kg/L = 8 Kg/L
