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

1.7 L

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.

i'm assuming that the correct answer is indeed the first one/ "a"..

it's filtration, but this is an assumption so my apologies if i got this
