to 95oC by burning 143 grams of methane, CH4, assuming

that 100% of the heat is used to heat the water.

The heat of combustion of methane is 891 kJ per mole

of methane. (The specific heat of water is 4.184 J/goC.)

I am not sure what to do

**DrBob222**, Monday, January 30, 2012 at 8:39pmHeat obtained from CH4 = 891 kJ x 143/16 = ? kJ.

?kJ = mass H2O x specific heat H2O x (Tfinal-Tinitial)

Solve for mass H2O and convert to kg.
