Medal .. Please help
how many grams of oxygen gas are required for the complete reaction of 24.2 grams of benzene (C6H6)?

benzene (C6H6) (l) + oxygen (g) carbon dioxide (g) + water (g)

? grams oxygen gas

Answer 1

1.) Balance the equation
2C6H6+15O2->12CO2+6H20

2.) Get moles of C6H6
24.2gramC6H6 * 2mole C6H6
78.112g C6H6
moles C6H6= .61957

3.) Get moles of O2, convert moles of C6H6 to O2 moles
0.61957 C6H6* 15 O2 moles
2 mole C6H6
moles O2= 4.6481

4.) 4.6481 moles O2 * 32.00 grams O2
15 moles O2
O2 grams= 9.91
