Question

Xcm³ of substance A which has a density of 0.8g/cm³ is mixed with 100cm³ of water with a density of 1g/cm³. The density of the mixture is 0.96g/cm³, Determine the volume X. ​

Answer 1

`x = 625 {cm}^(3)`

Step-by-step explanation:

mass of substance

`ms = (0.8)(x) = 0.8x \: kg`

mass of water

`mw = (100)(1) = 100 \: g`

density of solution

`d = 0.96 \: g {cm}^( - 3)`

Volume of X

`x = (0.8x + 100)/(0.96)`

`x = 625 \: {cm}^(3)`

I hope this answers your question.
