Question

Mass of Cu needed to make 2.0 moles of Cu2O? May anyone show work?

Answer 1

can u tell me the atomic mass of Cu and molar mass of Cu2O

Answer 2

@xkittybunnyx ?/???

Answer 3

atomic mass Cu = 63.5 and Molar mass Cu2O 143 thanks

Answer 4

so 143 gram of Cu2O has 2*63.5= 127 gram of Cu
so 2 mole(2*143) of Cu2O will have =2*143*127 / 143 = find now

Answer 5

mass = moles * molecular mass

so your moles is 2 and molecualr mass which is known as (M) is = 63.546(Cu) + (16*2) of O2
= 2 * 95.456
= 190.912g

Answer 6

Thanks but both of these answers or ways or different. May anyone else confirm?

Answer 7

u can consider mine one whee i converted whole thing from mole to weight
