Question

Рассчитайте массу 3 моль молекулы оксида углерода IV?

Answer 1

CO2
Mr(CO2)=12+2•16=44.
m=n•Mr=3•44=132 гр.

Answer 2

Дано:
n(CO2) = 3 моль
Найти:
m(CO2)

m(CO2) = n(CO2)*M(CO2)
M(CO2) = 44 г/моль
m(CO2) = 3 моль*44 г/моль = 132 г
Ответ: 132 г

Answer 3

Calculating the Molar Mass of Carbon Dioxide (CO2)

To calculate the molar mass of 3 moles of carbon dioxide (CO2), we can use the molar masses of the individual elements and then sum them up.

The molar mass of carbon (C) is approximately 12.01 g/mol, and the molar mass of oxygen (O) is approximately 16.00 g/mol.

Using this information, we can calculate the molar mass of carbon dioxide.

Molar mass of carbon dioxide (CO2): - Carbon (C): 12.01 g/mol - Oxygen (O): 16.00 g/mol

The molar mass of carbon dioxide (CO2) is the sum of the molar masses of carbon and oxygen, multiplied by the respective number of atoms in the molecule.

Calculation: - Molar mass of CO2 = (12.01 g/mol * 1) + (16.00 g/mol * 2) - Molar mass of CO2 = 12.01 g/mol + 32.00 g/mol - Molar mass of CO2 = 44.01 g/mol

Therefore, the molar mass of carbon dioxide (CO2) is approximately 44.01 g/mol.
