Use the equation 2cu+o2--> 2cuo to find how many grams of copper (ii) oxide would be formed from the complete reaction of .500 mol cu. question options: 42.1 39.8 44.5 34.7

(Answer) 39.77 g of copper (II) oxide would be formed from the complete reaction of 0.500 mol Cu.

Moles of Cu reacted = 0.500 mol

According to the balanced chemical equation, the mole ratio of copper and copper (II) oxide = 1: 1

Therefore, 0.500 moles of copper (II) oxide would be formed from the complete reaction of 0.500 mol Cu.

Mass of 0.500 moles of copper (II) oxide = (Number of moles x molar mass)

= (0.500 x 79.545) g = 39.77 g.

i think so it’s will be b yes i believe its

the maximum mass of nh3 is nh3 in grams
