Answer:

26.8g

Explanation:

The formula of the compound given is:

          Cu₂CrO₄

Given:

Number of moles  = 0.11

To find the mass, we use the expression below:

        Mass  = number of moles x molar mass

Molar mass of  Cu₂CrO₄ = 2(63.6) + 52 + 4(16) = 243.2g/mol

Now insert the parameters and solve;

 Mass  = 0.11 x 243.2 = 26.8g
