Please help with these chemistry question?
I really hope someone can help me and I would appreciate it if you can explain how you got the answer. Thanks
1.Using your knowledge of mole calculations, determine how many atoms there are in 1 litre of hexane or "gasoline." A litre of gasoline has a mass of approximately 850.0 grams. Assume that the molecular formula for gasoline is C6H14.
2.The analysis of a compound shows that it contains 21.9% sodium, 45.7% carbon, 1.9% hyrdrogen, and 30.5% oxygen. A mass spectrometre -- a device that measures molar mass--determines the molar mass to be 210 g/mol. What is the molecular formula of the compound.
