well, molarity is moles/liter
so somehow we have to turn liters of solution to mass.
grams of solute=2*39+32+64 * .4=179*.4=
grams of solute=71.6 grams check that.
approximate grams of water=1000.
So looking at those, it appears the density of the solution is very close to that of water, which gives us the mass of solution close to 1000 grams
Percent concentration=79.4/1000
The bottom line here is that you get a liter of solultion by sufficient water to bring the volume up to 1liter. Without its density it is impossible to calculate its mass. It most certainly is NOT 1000+79
What is the percent concentration of 0.4 M K2SO4 solution? Atomic mass: K-39g,S-32g, O-16g
