The molarity of 29% w/W of sulphuric acid, with a density of 1.22 g/ml is 3.61 M. According to the question, w/W% of sulphuric acid is 29% which means 29 g of sulphuric acid is dissolved in 100 g of solution

Therefore,

Density of sulphuric acid = 1.22 g/ml

Consequently, the molarity equation

Molarity = no. of moles/ volumes in liter

The number of moles = given mass/ molar mass = 29/98 moles since the molar mass of sulphuric acid is 98 g

The volume of sulphuric can be calculated by using the given density= 1.22 g/ml and mass=100 g:

Density = mass/volume

Substituting the values we get

Volume = mass/density = 100/1.22 mL

Volume in litres = 100/ (1.22 x 1000)

Therefore, Molarity = n/v

= 29/98/ 100/ (1.22 x 1000)

= (29 x 1.2 x 1000)/ (98 x 100)

= 3.61 M

### Uses of sulphuric acid
