Gaseous butane (CH3(CH2)2CH3) reacts with gaseous oxygen (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). If 0.256 g of water is produced from the reaction of 1.2 g of butane...

A solotuion contains 0.60 mg/mL Mn2+. What minimum mass of KIO4 must be added to 5.00 mL of the solution in order to completely oxidize the Mn2+ to MnO4-?

Using stoichiometry, calculate the volume of O2 gas at 1.25 atm and 18.0 ̊C, which forms when 10.5g KClO3 decomposes according to the reaction:2KClO3--> 2KCl + 3O2 Potentially useful information:...

Zinc(II) carbonate, ZnCO3, has a theoretical mass % CO2 of 35%. If 1.00 g of ZnCO3 reacts with excess HCl according to the procedure in this experiment, what mass of CO2 is lost as the ZnCO3 and HCl...

If I had 0.234mol of H2O, I was able to convert that into 4.22g and 1.41e23 molecules, which were both correct. But I wasn't able to calculate the number of total atoms in the sample. Isn't it just...
