Can you please explain #7 I really do get confuse when they say to look for m and I don't know what to use 

6. What mass of NaCl is dissolved in 200 g of water in a 0.100 m solution? the free2ing point of solution is lower than the true. This means that The ATF will we high and the molar mass Of solute would be loww. would the calculated molar mass of the solute have been too high or too low?
