Question

a) ravi prepared a solution of sodium chloride by mixing 5.85 gm of salt in one litre of water .find:
1)molar mass of sodium chloride
2) number of moles of sodium chloride dissolved .( atomic mass of Na=23u, Cl=35.5u
)

Answer 1

(a) Molar mass of sodium chloride (NaCI) = atomic mass of sodium (Na) + atomic mass of chlorine (Cl) = 23 + 35.5 u= 58.5 u= 58.5 g        (b) Number or moles   (c) Concentration of solution  ( Density of water is taken 1000 g/L)
