Question

[Ans. 2000 kg /m] f. If the mass of a substance having its volume 80 cm is 68 g. Calculate the density of the substance. Ans. 0.85 g/cm3]​

Answer 1

• Mass = 68 g
• Volume = 80 cm
• We know,
• 
  `density \: \: = (mass)/(volume)`
• Therefore, the density of the substance
• 
  `= (68)/(80) \: \: g \: \: \: {cm}^( - 3) \\ = (17)/(20) \: \: g \: \: \: {cm}^( - 3) \\ = 0.85\: \: g \: \: \: {cm}^( - 3)`

The density of the substance is

`0.85\: \: g \: \: \: {cm}^( - 3)`

Hope you could get an idea from here.
