Question

Liquid A has a density of 0.7 g/cm³.

Liquid B has a density of 1.6 g/cm³.
140 g of liquid A and 128 g of liquid B are mixed to make liquid C.
Work out the density of liquid C.

Answer 1

0.957g/cm3

Explanation:

Density*Volume= mass

volume=mass/density

Liquid A= 140g/0.7

=200

Liquid B= 128/1.6

=1.6

Volume of liquid C= 200+80

=280

Mass of liquid C= 140+ 128

=268

Liquid C's density= mass/volume

=268/280

=0.957g/cm3

I hope I helped :)
