Question

A liquid has density 1.5 g/cc. 50 cc of it is mixed with 30 cc of water. What will be the density of mixture solution?​

Answer 1

Answer:

1.3125 g/cc

Explanation:

density = mass/volume = m/v

d = m/v

mass of liquid = d1v1 = 1.5x50 = 75 g

mass of water = d2v2 = 1.0x30 = 30 g

density = mass/volume = 105 / 80 = 1.3125 g/cc

Answer 2

Given,

Density of liquid (da) =1.5g/cc.

Density of water (dw) =1g/cc.

Volume of liquid (va) =50cc.

Density of water (vw) =30cc.

Density =mass/volume

Mass =density x volume

So,

Mass of liquid =Density of liquid x Volume of liquid

=1.5 x50

=75g

Mass of water =Density of water x Density of water

=1 x 30

= 30g

Total mass =75 +30

=105g

Total volume =50 +30

=80cc

Density of mixture =total mass /total volume

=105/80

=1.3125gm/cc

Hope it help you
