Question

Liquid A has a density of 1.2 g/cm^3

150 cm^3 of Liquid A is mixed with some of Liquid B to make Liquid C.

Liquid C has a mass of 220 g and a density of 1.1 g/cm
Find the density of Liquid B.

Answer 1

0.8g/cm³

Explanation:

1.2g/cm³*150cm³=180g

180g+x=220g

x=40g

220/1.1=200

150cm³+y=200cm³

y=50cm³

40g/50cm³=0.8g/cm³
