60 g of HCL will make how many L of 2.5M HCL? (Molar Mass of HCL = 36.5g/mol)

0.66 L

Explanation:

The molarity of a solution is given by:

(1)

where

M is the molarity of the solution

n is the number of moles of the solute

V is the volume of the solution

In this problem we have:

is the mass of the solute (HCl)

is the molarity of the solution

We also know that the molar mass of HCl is

So, we can find the number of moles of HCl:

And so using eq(1), we find the volume of the solution:

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
