What is the volume of a 0.125 M solution that contains 25g of CaCO3?
0 0.000625 L
O 200. L
0 2.00 L
0.500 L

Answer 1

Sln

n=m/mr

n=25/100

n=0.25mole of Caco3

Malality =number of moles/volume (divided by number of moles both sides)

volume =Malality /number of moles

v=0.125/0.25

v=0.500L

I hope this help
