Question

calculate the mole of copper oxide obtained from 110 gram of CuSo4.
2CuSo4 ------->2CuO+2SO2+O2​

Answer 1

Answer:

I don't no it's ok brother

Answer 2

Explanation:

mass of CuSO4 = 110g

molar mass of CuSO4 = cu + S + O(4)

64.5 + 32 + 16(4) = 159..5g/mol

As we have formula

• (n) = mass÷ molar mass

= 110g ÷ 159.5g/mol

(n) = 0.6896 mol

now using equivalency (conversion factor),. we see that.

2 mol of CuSO4 =~ 2 mol of CuO

then

0.6896 mol of =~ 0.6896 mol of Cuo

To find mass of 0.6896 mol of CuO ,

we have formula

(n) = mass ÷ molar mass

now by cross multiplication

mass = (n) × molar mass. (63.5 molar mass of Cu)

mass = 0.6896 mol × 63.5 g÷mol

mass = 47.78 g
