Thermochemistry: Heating water with Methane

I'm stuck on this one
 
How many grams of methane must be combusted to heat 1.00 kg of water from 25.0 °C to 90 °C, assuming H2O(l) is the product of the reaction and no heat is lost to the surroundings?
 
So far I have 
1000 g H2O
ΔT = 65.0 °C
q = 0
 
CH(g) + 2O2 (g) → 2H2O (l) + CO2
 
heat evolved = 4.1798 J g-1 °C-1 (1000g)(65.0°C)(1kJ/1000J) = 271.6 kJ
