Question

What mass of cacl2 will be formed when 250 ml of 0.76 molarity hcl we have 2000 ram of csu 3?

Answer 1

If we were to look at the definition of molarity then we can see that the number of moles get calculated for almost 1000 ml of solution.

We see that 1000ml of 0.75 m hcl has 0.75 mol.

So if we were to take 25 ml of the 0.75m of hcl then after going through all the steps the answer would be 0.009375 mol of CaCO3
