Answer:

→ 22.9 g of N2.

Explanation:

→ The molar mass of CuO is 63.5 + 16 = 79.5

→ The molar mass of N2 is 2×14 = 28

According to the equation, for every 3 molecules of CuO, one molecule of N2 is made.

Therefore,

3×79.5 g of CuO make 28 grams of N2.

Therefore,

195 g of CuO make

[tex]28×(195/3×79.5) = 22.9 g of N2.[/tex]
