The number of moles in exactly 64 grams of oxygen (O2) is two.
Balance: C4H8S2 + O2 --> CO2 + H2O + SO3 Work out how many S, C and H on the left and then balance for the right. Then add up how many O this gives on the right and divide by 2 to get number of O2. C4H8S2 + 9O2 --> 4CO2 + 4H2O + 2SO3
The oxygen is a diatomic molecule - O2.
There are approx 6.02 X 1024 oxygen atoms. --> 5mol CO2 (2mol O2/ 1mol CO2)= 10 mol O2 Then Avagadro's number is used to calculate the number of atoms.... 10 mol O2 (6.02 X 1023/ 1mol) = 6.02 X 1024
CH4+O2 --- CO2+H2O... All that's missing - is the number 2 before the water molecule... CH4+O2 --- CO2+2H2O
O2 offers several ways to top up a prepaid phone. One can schedule an automatic top up for a specific amount on a specific day. Or one can go online or use a phone to pay by debit or credit card.
