Question

2 liquids of density 0.8g/cm³ and 1.2g/cm³ are mixed in equal mass .Find combined density ​

Answer 1

Answer:

Let the liquid be 2m am and 3m gm respectively. therefore, the volume of the first

liquid of density 2.5gm /cm 3is V1= 2m/2.5m cm³

That of the second liquid is V2=3cm/0.8 cm³

Total volume V=V1+V2=2m/2.5+3m/0.8cm³

Total mass =2m+3m=5mgm

Therefore, the average density

ρav=V5m=2.52m+0.83m5m=2.52+0.835=gm cm3=1.3.
