Question

Какое количество вещества содержится в углероде массой 36г

Answer 1

Дано:
m=36 г
М = 12 г/моль - молярная масса углерода
__________
v-?

По формуле:
v=m/M
находим:
v=36/12= 3 моля

Ответ: 3 моля углерода

Answer 2

Calculating the Amount of Substance in Carbon

To calculate the amount of substance in carbon with a mass of 36g, we can use the formula:

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

The molar mass of carbon (C) is 12.01 g/mol.

Using the given mass of 36g, we can calculate the amount of substance in moles:

Amount of substance = 36g / 12.01 g/mol

Amount of substance ≈ 3 moles

This calculation is based on the molar mass of carbon and the given mass of 36g
