How many grams of carbon can react with 2.24 liters of hydrogen if the metal ch4 is formed.

Let’s execute the solution:
1. Let us write down the equation according to the problem statement:
C + 2H2 = CH4 – reaction of the compound, methane was obtained;
2. Let’s calculate the number of moles of hydrogen, carbon:
1 mole of gas at normal level – 22.4 liters;
X mol (H2) -2.24 L. hence, X mol (H2) = 1 * 2.24 / 22.4 = 0.1 mol;
X mol (C) – 0.1 mol (H2);
-1 mol -2 mol from here, X mol (C) = 1 * 0.1 / 2 = 0.05 mol.
3. Find the mass of carbon:
M (C) = 12 g / mol;
m (C) = Y * M = 0.05 * 12 = 0.6 g.
Answer: to carry out the reaction, carbon weighing 0.6 g is required.
