how many grams of amonia will have the same number of molecules as 15g of benzene?

give the IUPAC name of each of the following coordination compounds:
[Pt(NH3)4Cl2;
[Pt(NH3)2Cl2];
K2[PtCl6];
Co(NH3)5Cl]Cl2;
K2[Co(H2O)(CN)5];
[Fe(H2O)5(OHO)2+

calculate the percentage of each element in the following compounds:- CH20,and NH4N3

draw the modern periodic table,then show metals,metalloids,non metals,and s,p,d,f block in the periodic table

state the discovery of the electrons,protons,and neutrons

state postulates of daltons atomic theory and compare it with the modern explanation

Consider the reaction
C6H12 + 9 O2 –> 6 CO2 + 6 H2O
How many grams of O2 are consumed when C6H12 is burned to yield 2.5 grams of CO2?

Give your answer in 1 decimal.

It said this when I got the wrong answer: Calculate the number of moles of CO2 produced in the reaction. Then match the number of moles of O2 and the corresponding number of grams of O2. Do not forget the reaction stoichiometry.
The correct answer is: 2.7

But I still dont know how to get the answer.
