Hey there!
Cu(CN)₂
Find the molar mass.
Cu: 1 x 63.546 = 63.546
C: 2 x 12.01 = 24.02
N: 2 x 14.07 = 28.14
-----------------------------------
115.706 grams
The mass of one mole of Cu(CN)₂ is 115.706 grams.
We have 4 moles.
115.706 x 4 = 463
4.00 moles of Cu(CN)₂ has a mass of 463 grams.
Hope this helps!
Ch = sh = why and find the stuff
2 Al+ 3 CuO-> 1 Al2O3+ 3Cu
Answer:
I attached a photo of balanced equations but thats as much as I can help.
Explanation:
M/V=D
16.52/2.26=D
