Question

15. How many grams are equal to 0.11 mole of copper(1) chromate, Cu2(CrO4)? with work please​

Answer 1

26.8g

Step-by-step 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
