Question

Martha has a large amount of 1.25 M H2SO4 in her lab. She needs 36 grams of H2SO4 for a chemical reaction she wants to perform. How many liters of solution should she use?

Answer 1

Data:

Molarity, M = 1.25 M

mass, m = 36 grams

Solute, H2SO4

Formulas:

M = n / V => V = n / M

n = mass in grams / molar mass

Solution:

molar mass of H2SO4 = 98.079 g/mol

n = 38 g / 98,079 g/mol = 0.3874 mol

V = 0.3874 mol / 1.25M = 0.31 liter

Answer: 0.31 liter

Answer 2

Answer:

0.29 L

Explanation:

Just confirming this.
