my homework is due in a few hours and I am confused. Please... help... quickly!

Sodium chlorate decomposes into sodium chloride and oxygen gas as seen in the equation below. 

 

­­2NaClO3­ --> 2NaCl +3O2

 

How many grams of NaClO3­ were needed to produce 6 grams of O2? Round your answer to the nearest whole number.

Round your answer to the whole number. If your answer is a whole number like 4, report the answer as 4.0

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Element Molar Mass
Sodium 23
Chlorine 35.5
Copper 63.5
Oxygen 16
