Question

41.7 g of a substance are added to a graduated flask containing 523 ml of water The

water level rises to the 56.8 ml mark. From this information, calculate the density and
specific gravity

Answer 1

9.266 gm/ml is the density of the substance. 9.266 is the specific gravity of the substance.

Step-by-step explanation:

Data given:

mass of the substance = 41.7 grams

initial volume of water = 52.3 ml

volume after adding the substance = 56.8 ml

volume of the metal = 56.8 - 52.3 = 4.5 ml

density =?

specific gravity =?

density is calculated by using the following formula:

density =
`(mass)/(volume)`

=
`(41.7)/(4.5)`

density = 9.266 gm/ml

The ratio of density of the substance with the reference substance density is called specific gravity. In this case the reference substance is water which has density of 1 gm/ml at 4 degrees.

so specific gravity =
`(density of substance )/(density of water)`

putting values in above equation:

specific gravity =
`(9.266)/(1)`

= 9.266 (no units as both denominator and numerator has same units and got cancelled)
