Answer: A) 0.20 L

Step-by-step explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to the neutralization law,


M_1V_1=M_2V_2

where,


M_1 = molarity of stock
H_2SO_4 solution = 10.0 M


V_1 = volume of stock
H_2SO_4 solution = ?


M_2 = molarity of dilute
H_2SO_4 solution = 0.50 M


V_2 = volume of dilute
H_2SO_4 solution = 4.0 L


10.0* V_1=0.50* 4.0


V_1=0.20L

Therefore, the volume of 10.0 M
H_2SO_4 solution needed to prepare 4.0 L of 0.50 M
H_2SO_4 is 0.20 L
