What is the molarity of $H_{2} SO_{4}$ solution that has a density of $1.84 g / cc$ at $3 5^{\circ} C$ and contains $98%$ by weight?

Options:

Answer:

Solution:

Molarity $= \frac{wt. of solute}{mol. wt.} \times \frac{1000}{vol. of solution (in mL)}$ (Volume of solution $= \frac{mass}{density} = \frac{100}{1.84} = 54.34 mL$ ) Now, molarity $= \frac{98}{98} \times \frac{1000}{54.34} = 18.4 M$
