Answer 1

Answer #1

use:

number of mol = number of molecules / Avogadro’s number

number of mol = 1.48*10^25 / 6.022*10^23 mol

number of mol = 24.58 mol

Molar mass of I2 = 253.8 g/mol

use:

mass of I2,

m = number of mol * molar mass

= 24.58 mol * 2.538*10^2 g/mol

= 6.238*10^3 g

Answer: 6.24*10^3 g
