Question

a sulphuric acid solution contains 98% of sulphuric acid by mass. Calculate the molarity of this solution given that its density is 1.84g/cm3 ​

Answer 1

Answer:

Explanation:

Molarity is 98 percent

⇒For every 100g water, there is 98g of sulphuric acid.

Density of the solution is 1.84g/cm³

Volume = $\frac{mass}{density}$

∴Volume(in mL) for 100g of solution= 100÷1.84

                                                           ≈54.35mL

Molarity=$\frac{mass}{molar mass}$×$\frac{1000}{volume in mL}$

∴Molarity=$\frac{98}{98}$×$\frac{1000}{54.35}$

Molarity=18.4M(approx.)
