Calculate Molar Mass of Sodium Iodide:149( g/mol)
1 Mole of NaI--->149grams
0.365 Mole Of NaI---> x grams
x=0.365*149/1
x=54.385 grams
Mass of Solution=Mass Of Water+Mass Of Sodium Iodie
1 Gram Represent 1 cm^3
Mass of Solution=275+54.385
=329.385 grams
The Solute Here is the sodium iodide and the solvent is Water 
mass percent of solute in the solution would be calculated
Total Mass of Solute/Total Mass of Solution
