Question

Визначте кількість речовини метану масою 5 грам​

Answer 1

Ответ:

Объяснение:

Дано

m(CH4)=5 г

М(СН4) = 16 г/моль

Найти

n(CH4)

n(CH4) = m / M = 5 г / 16 г/моль = 0,3 моль

Answer 2

Calculating the Amount of Methane

To determine the amount of substance, we can use the formula:

Amount of substance (in moles) = Mass of substance / Molar mass

Given: - Mass of methane = 5 grams - Molar mass of methane (CH4) = 16.04 g/mol

Calculation

Using the formula, we can calculate the amount of methane:

Amount of substance (in moles) = 5 g / 16.04 g/mol

Amount of substance (in moles) ≈ 0.312 moles

Therefore, the amount of methane with a mass of 5 grams is approximately 0.312 moles.
