There are 5 protons in Boron 1.
To form CuO - 100 g of Copper reacts with 25 g of Oxygen
then amount of CuO formed - 125 g
Since excess oxygen is provided, Copper is the limiting reactant. Then Copper is completely consumed during the reaction and amount of product formed depends on the amount of Copper used.
So if 100 g of Copper makes up 125 g of CuO
Then 140 g of Copper will form - 125/100 x 140 = 175 g of CuO
Answer:
.46 moles
Explanation:
PV = n RT make sure you use the correct R = 8.31446 L-kPa/(K-mol)
36 * 38 = n * 8.31446 * (273.15 + 82)
n = .463 moles
