Answer:
1.58gcm⁻³
Explanation:
Given parameters:
Volume of sample = 1.00L
Mass of sample = 1.58kg
unknown:
Density of the sample
Solution:
The density of a substance is expressed as its mass per unit volume.
The units of the parameters are given for volume as liters and for mass as kg.
We need to convert to cm³ for volume and into g for the mass:
1L = 1000cm³:
Therefore, the volume of the sample is 1000cm³
For the mass:
1kg = 1000g
1.58kg gives 1.58 x 1000g = 1580g
The density of the sample will be:
Density =
Density = = 1.58gcm⁻³
