volume of butane = 5.10ml
density of butane = 0.579g/ml
mass of butane = volume * desnity
= 5.10*0.579 = 2.9529g
a.
2C4H10(g) + 26O2(g) -------------------> 8CO2(g) + 10H2O(g)
2 moles of C4H10 react with 26 moles of O2
2*58g of C4H10 react with 26*32g of O2
2.9529g of C4H10 react with = 26*32*2.9529/(2*58) = 21.18g of O2
b.
2C4H10(g) + 26O2(g) -------------------> 8CO2(g) + 10H2O(g)
2 moles of C4H10 react oxygen to gives 10 moles of H2O
2*58g of C4H10 react with oxygen to gives 10 moles of H2O
2.9529g of C4H10 react with oxygen to gives = 10*2.9529g/(2*58g) = 0.2545 moles of H2O
c.
2C4H10(g) + 26O2(g) -------------------> 8CO2(g) + 10H2O(g)
2 moles of C4H10 react oxygen to gives 8 moles of CO2
2*58g of C4H10 react with oxygen to gives 8 moles of CO2
2.9529g of C4H10 react with oxygen to gives = 8*2.9529/(2*58) = 0.2036moles of CO2
total no of moles = 0.2545 mole + 0.2036 moles = 0.4581 moles
total no of molecules = no of moles * 6.023*10^23
= 0.4581*6.023*10^23
= 2.76*10^23 molecules >>>>>answer

Butane is a common fuel used in cigarette lighters and camping stoves. Normally supplied in metal containers under pressure, the fuel exists as a mixture of liquid and gas, so high temperatures may cause the container to explode. At 25.0 ° C, the vapor pressure of butane is 2.30 atm. What is the pressure in the container at 128.0 ° C? ( ? H ° vap = 24.3 kJ/mol.)
1) Butane, C4H10, is a component of natural gas that is used as fuel for cigarette lighters. The balanced equation of the complete combustion of butane is 2C4H10(g)+13O2(g)→8CO2(g)+10H2O(l) At 1.00 atm and 23 ∘C, what is the volume of carbon dioxide formed by the combustion of 2.60 g of butane? 2)How many air molecules are in a 10.0×12.0×10.0 ftroom? Assume atmospheric pressure of 1.00 atm, a room temperature of 20.0 ∘C, and ideal behavior. Volume conversion:There are 28.2 liters in...
