Question

what is the total number of moles of H2SO4 required to prepare 5 litre of 0.2 M solution​

Answer 1

Answer:

molarity = no of moles/ volume of solution (in L)

0.2M. = no of moles / 5L

no of moles of H2SO4=. 0.2mole/L. *5L

=. 1mole

Answer 2

Here's your answer!

• Volume of the solution, V = 5 litre

• Molarity of solution, M = 0.2 M

• Number of moles, n = ?

By using formula,

• Molarity = Moles of solute ÷ Volume of Solution.

• M = n ÷ V

• 0.2 M = n ÷ 5 L

• n = 0.2 × 5

• n = 1 mole
