How many moles of water are produced from the reaction of 50. 0g of methane.

Sagot :

Answer:

Given the balanced equation

CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

we know that we'll get one mole CO2 for every 1 mole CH4.  So let's calculate how many moles are in 50 g of CH4 by dividing it's mass by it's molar mass (16 g/mole).  I get 3.125 moles.  The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles.  Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole).  We should expect 138 grams of CO2.
