Question

If 1.27gm Cu is obtained by reduction of one sample of cu2o then the amount of oxygen in sample is .... gm​

Answer 1

Answer:

$we \: know \: that \: in \: cu_{2}o \: ratio \: of \: cu \: and \: o \: is \: 2 \: ratio \: 1$

↪ hence cu : o (in cu2o) = 2:1

️↪️ 1.27 : 1.27/2

↪️6.37

↪️hence amount of oxygen in sample = 6.37 gm
