Explanation / Answer

Molar mass of I2 = 253.8 g/mol

mass of I2 = 48.8 g
mol of I2 = (mass)/(molar mass)
= 48.8/253.8
= 0.1923 mol



According to balanced equation
mol of NaI required = (2/1)* moles of I2
= (2/1)*0.1923
= 0.3846 mol


Molar mass of NaI,
MM = 1*MM(Na) + 1*MM(I)
= 1*22.99 + 1*126.9
= 149.89 g/mol


mass of NaI = number of mol * molar mass
= 0.3846*149.89
= 57.6 g
Answer: 57.6 g
