Answer:
Number of moles of oxygen used=13.5moles
Explanation:
To know the number of moles of oxygen used, first calculate the molar mass of water.
H2O=(2*1)+(1*16)
=2+16
18g/mol of H2O
The moles of H2O is 7.6 moles
So first, find the molar mass of oxygen
O2=2*16
=32g/mol
Then, number of moles of oxygen is equal to molar mass of oxygen divide by the molar mass of water times the number of moles of water
No. moles of O2=[32g/mol]/[18g/mol] *7.6moles
Moles of O2=1.778*7.6moles
No.moles of O2=13.5 moles
Therefore, the number of moles of oxygen used was 13.5moles
