Question

What is the molarity of 245.0 g of H2SO4 dissolved in 1.000 L of solution?

(a) 2.408 M

(b) 2.508 M

(c) 2.598 M

(d) 2.498 M

This question was addressed to me in an interview.

My question comes from Yields in Cell Culture in portion Homogenous Reactions of Bioprocess Engineering

Answer 1

Correct answer is (d) 2.498 M

For explanation I would say: MV = grams / molar mass

(x) (1.000 L) = 245.0 g / 98.0768 g mol^-1

x = 2.49804235 M

to four sig figs, 2.498 M.
