molar mass of sucrose ... 342 g
molarity = moles per liter = (4 / 342) / .35
% mass = [4 g / (4 g + 350 g)] * 100%
A 4g of sugar cube sucrose (C12 H22 O11) is dissolved in a 350ml teacup of 80 degree census of water
1: What will be the molarity of the sugar
2:What is the percentage composition by mass of the sugar

I assume you meant 80 Celsius.
M = mols/L and mols = grams/molar mass
mols C12H22O11 = 4/342 = estimated 0.013
mols/L = estimated 0.013/0.350 = ?
%by mass = grams sugar/100 g solution
(4/354)*100 = ?
