CHEMISTRY question !?

33.6 L of CH4 are combusted under a dish containing ice. change in Hrxn for the combustion of CH4 is -802kJ/mol. How many grams of ice can you melt if none of the heat is lost to the environment? (change Hfus=6.00 kJ/mol)

Calculate how many moles are in 33.6 L.

Moles X 802kJ/mol = total heat.

Total heat / 6.00 kJ/mol = moles of ice

moles of ice X mol wt. of ice = grams of ice melted
