# What is the mass (in grams) of carbon required to react with water to form 1.00 mol CH4(reaction given below)? Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2 C (s) + 2 H2O (l) --> CH4 (g) + CO2 (g) 1. 48 g C 2. 24.0 g C 3. 12.0 g C 4. 24.02 g C

The correct answer is option B
From the equation:
2C(s) + H2O (l) (CH4 (g) + CO2 (g)
We can tell that 2 moles of carbon are required to react with water to form 1.00mol CH4.
12 grams of carbon is equal to 1 mole.
Since we have two moles
Total amount of carbon require for this reaction
12 grams 2
= 24
= 24.0gC.   John Smith 24.0 g C

Given: 1.00 mol CH4 Unknown: ? g C 1.00 mol CH4 x (2 mol C/1 mol CH4) x (12.01 g/mol C) = 24.02 = 24.0 g C Although 24.02 g C is technically correct, your answer must include the correct number of significant figures (which in this instance is 3). The answer is rounded to 24.0.    Search for Google images Select a recommended image
