Question

How many liters are needed to make a 1.5 M solution with 2.5 moles of HCL

Answer 1

1.7 L

Step-by-step explanation:

1.5M = 1.5 mol/1L

1.5 M means that 1 L solution has 1.5 mol HCl

1.5 mol HCl ----- 1 L

2.5 mol HCl ---- xL

x=(2.5*1)/1.5 ≈ 1.7 L solution, so we need 1.7 L of water to make 1.7 L of solution.
