Numerical problems.

16. Calculate the density of a solid from the following data:

Mass of the given solid = 84.2 g, initial volume of water in a graduated cylinder = 36 mL and final volume of water and
solid in the graduated cylinder = 60 mL.​

Answer 1

Explanation:

Density = mass/volume

= 84.2/(60-36)

= 84.2/24

= 3.51 g/ml

Answer 2

Answer:

ans)Initial volume of water in a graduated cylinder = 36 mL

final volume of water and

solid in the graduated cylinder = 60 mL.

Volume of solid=final volume of water and

solid in the graduated cylinder- Initial volume of water in a graduated cylinder=

=60ml-36ml=24ml

Mass=84.3g

Density =84.3/24

3

=3.5125 g/cm
