we know that,
molarity=(given mass/molar mass)*(1000/volume of solution in ml)
all the dats are given,only we have to find out the given mass or the present mass of the KCl.
1.25=(given mass/74.5)*(1000/750)
=> given mass=(1.25*750*74.5)/1000
=69.84g.

What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
