Suppose a certain compound contains only hydrogen and oxygen. Analysis of a 10.00 g sample of this compound revealed that the sample contained 8.88 g of oxygen. A. How many grams of hydrogen does the sample contain? Show your work here. B. Convert the grams of oxygen (8.88 g) to moles of oxygen. Show your work below and include units on each number in the calculation. (From the periodic table, oxygen's molar mass is 16 g/mol) C. Convert the grams of hydrogen (that you calculated first) to moles of hydrogen. Show your work below and include units on each number in the calculation. (From the periodic table, hydrogen's molar mass is 1 g/mol) D. Now that you know the number of moles of oxygen (O) and the number of moles of hydrogen (H) the 10.00 g sample contained, what is the H to O molar ratio of this compound? E. Based on this H to O molar ratio, what is the simplest formula of this compound?

Suppose a certain compound contains only hydrogen and oxygen. Analysis of a 10.00 g
sample of this compound revealed that the sample contained 8.88 g of oxygen.
A. How many grams of hydrogen does the sample contain? Show your work here.
B. Convert the grams of oxygen (8.88 g) to moles of oxygen. Show your work below and
include units on each number in the calculation. (From the periodic table, oxygen's
molar mass is 16 g/mol)
C. Convert the grams of hydrogen (that you calculated first) to moles of hydrogen. Show
your work below and include units on each number in the calculation. (From the
periodic table, hydrogen's molar mass is 1 g/mol)
D. Now that you know the number of moles of oxygen (O) and the number of moles
of hydrogen (H) the 10.00 g sample contained, what is the H to O molar ratio of this
compound?
E. Based on this H to O molar ratio, what is the simplest formula of this compound?
In today's experiment you will begin with a compound containing only copper and chlorine,
and determine the grams of copper in a sample of the compound. Then you will do the
same calculations as above in order to determine the simplest formula for the copper/
chlorine compound.
