Question

calculate the number of mole of methane required to be burnt to produce 9gm of water.​

Answer 1

Answer:

ch4 +202 = co2 + 2h2o

16 g ch4 gives 36 g of water

by unitary method

9g of water will be produced by 4 g of methane

moles of methane req = mass/molar mass

moles = 0.25

Answer 2

Explanation:

CH4+2O2=CO2 + 2H2O

16g CH4 gives 36g of H2O by unitary method.9g of H2O will be produced by 4g methane moles of methane req= mass/ molar mass moles =0.25
