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

marysya [2.9K]

The mass of the product is <em>98.78 g.</em>

The word equation is

aluminum + chlorine → product

20.00 g + 98.78 g → <em>x</em> g

If each reactant is completely consumed, the <em>Law of conservation of Mass </em>tells us the mass of the product must be 98.78 g.
