I can do questions in the format of:
1.4g of nitrogen combined with 0.30g of oxygen
But I really can't get my head around these types of questions:
0.69g of sodium forms 0.93g of an oxide of sodium
0.24g of carbon combines with 0.64g of oxygen
Any help, as little as possible would be appreciated![]()

"0.69g of sodium forms 0.93g of an oxide of sodium"
So there'll be 0.69g of Na, and 0.93g-0.69g = 0.24g of O
"0.24g of carbon combines with 0.64g of oxygen"
Surely this is the same as the first question format you mentioned? -
