What mass of methane (in g) must be burned in order to liberate 12567 kJ of heat?

Mass of methane required in gram = 226.35 gram (Approx.)

Explanation:

Given:

Heat energy used = 12,567 kJ

Missing data;

Δcombustion = 891  kJ/mol

Find:

Mass of methane required in gram

Computation:

Number of mol methane burned = Heat energy used / Δcombustion

Number of mol methane burned = 12,571 / 891

Number of mol methane burned = 14.1088 mol

1 mol of methane in gram = 16.043 grams

So,

Mass of methane required in gram = Number of mol methane burned x 1 mol of methane in gram

Mass of methane required in gram = 14.1088 x 16.043

Mass of methane required in gram = 226.3474

Mass of methane required in gram = 226.35 gram (Approx.)

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
