Question

How many grams of HCl are needed to make 500.0 mL of a 1.00 M solution (GMW HCl = 36.46 g)

Answer 1

We know that:

Where, w= weight, M= molarity, E= equivalent weight and V= volume.

It is given that the molarity of HCl is 1 M with equivalent weight 36.46 g. Thus the amount of HCl (in g) needed to make 500 ml of solution will be calculated as:

w= 18.23 g

Therefore, 18.23 g of HCl is required to form 500 ml of 1 M HCl solution.
