Question

2.50 g CuCl2 equals how many moles

Answer 1

Step-by-step explanation:

Number of moles is defined as the mass of substance given in grams divided by the molar mass of substance.

It is given that mass of
`CuCl_(2)` is 2.50 g and molar mass of
`CuCl_(2)` is 134.45 g/mol.

Therefore, calculate number of moles as follows.

Number of moles of
`CuCl_(2) = (mass)/(molar mass)`

=
`(2.50 g)/(134.45 g/mol)`

= 0.0186 mol

= 0.019 mol (approx)

Thus, we can conclude that 2.50 g CuCl2 equals 0.019 moles (approx).

Answer 2

the molar mass of CuCl2 is 134.45 g/mol; therefore, you divide 2.5 g of CuCl2 by 134.45 g of CuCl2 leaving you with 0.019 moles
