Question

A student performs an experiment with three unknown fluids and obtains the following measurements: Fluid A: m = 2060 g, V = 2000 mL Fluid B: m = 672 g, V = 850 mL Fluid C: m = 990 g, V = 1100 mL find density

Answer 1

Given:

Fluid A - mass(m) = 2060 g and volume (V) = 2000mL

Fluid B - mass(m) = 672 g and volume (V) = 850mL

Fluid C - mass(m) = 990 g and volume (V) = 1100mL

To Find:

the density of the given fluids =?

Solution:

We know that density can be calculated as

density = mass/volume

using the above formula, density can be calculated as follow

• For fluid A
• density = m/V = 2060/2000 = 1.03 g/mL

• For fluid B
• density = m/V = 672/875 = 0.768 g/mL

• For fluid C
• density = m/V = 990/1100 = 0.9 g/mL
