4.00 g of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of 160g mol, is burned completely in excess oxygen, and the mass of the products carefully measured:
product mass
carbon dioxide 6.60 g
water 1.80 g
Use this information to find the molecular formula of x.
This is the chemical formula for talc (the main ingredient in talcum powder):
Mg3(Si2,O5)2(OH)2
An analytical chemist has determined by measurements that there are 26 moles of silicon in a sample of talc. How many moles of hydrogen are in the sample?
An unknown compound has the following chemical formula
H2,Ox
where x stands for a whole number.
Measurements also show that a certain sample of the unknown compound contains 9.0 mol of oxygen and 18.07 mol of hydrogen. Write the complete chemical formula for the unknown compound.
