Calculate the number of moles, n, of CuCl₂.2H₂O in 0.12 g of copper (II) chloride dihydrate:

• Determine molecular mass, M, of CuCl₂.2H₂O (record your answer to 1 decimal place) g mol^-1 
• Determine the number of moles, n, in 0.12 g of CuCl₂.2H₂O

Record your answers in scientific notation (i.e. 6.1E-9) to two significant figures:  moles
