Question

how many ml of sulphuric acid of density 1.84g/ml and mass percent 95 .6 should be added to one litre of sulphuric acid of density 1.31 gml/1 and mass percent 40 to obtain sulphuric acid of density 1.40gml/ and mass percent 50 ?

Answer 1

Answer:

3.4ml

Explanation:

We need to find the volume of sulphuric acid with respective densities.

Volume of sulphuric acid whose density is 1.84 is calculated using the relationship:

Volume= Masss/ Density

But mass of the acid is calculated as:

100×98/97

=101g

Volume=101g/1.84g/ml

=54.9ml

Similarly, volume of sulphuric acid with specific density of 1.31g/ml is determined using the same procedure:

Mass= 100×98/40

=245g

Hence, volume = 245g/1.31g/ml

=187.02ml

Using the concept of dilution of solution of known concentration, M1V1=M2V2

1×187.02=55.7V2

V2= 3.4ml
