For a chemical reaction, you require 1 mole of CH4. Your bottle contains 19 grams. Do you have enough? Pick the statement that is correct.

A reaction of 19g of CH4 would yield 1.185mole of CH4, so, yes we have enough

Explanation:

To know if you have enough CH4, let us find the number of mole of CH4. This is illustrated below:

Mass of CH4 = 19g

Molar Mass of CH4 = 12.01 + (1.00784 x 4) = 12.01 + 4.03 = 16.04g/mol

Number of mole = Mass /Molar Mass

Number of mole = 19/16.04 = 1.185moles.

From the calculation above, the number of mole of CH4 obtained is 1.185moles. Therefore, we have enough
