For the reaction C + 2H2 → CH4, how many grams of hydrogen are required to produce 4.1 moles of methane, CH4

Explanation:

Start by determining the mole ratio of CH4 and H2; it can be on these form and use the appropriate ratio depending on your desired unit;

1molCH42molH2

or

2molH21molCH4

Once known, multiply the value to the mole of CH4 as provided in the problem to find the mole of H2;

0.6 mol CH4 x## ?

Then, find the molar mass of H2 to use to find the mass of H2 needed to produce CH4.

The answer is 2.4 grams of H2

your parents i think this could be it

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
