Question

Какое количество вещества содержится в 33г оксида углерода (IV) ?

Answer 1

Формула оксида углерода (IV) CO2
n=m/M, где n-кол-во вещества, m-масса, М-молярная масса
М=Ar(C)+2*Ar(O)=12+2*16=12+32=44г/моль
n=33/44=0.75моль

Answer 2

Calculation of the Amount of Substance in 33g of Carbon Dioxide (IV)

To calculate the amount of substance in 33g of carbon dioxide (IV), we need to use the molar mass of carbon dioxide (IV) and the formula:

Amount of Substance (n) = Mass (m) / Molar Mass (M)

The molar mass of carbon dioxide (IV) can be calculated by summing the atomic masses of its constituent elements. Carbon has an atomic mass of 12.01 g/mol, and oxygen has an atomic mass of 16.00 g/mol. Since carbon dioxide (IV) has one carbon atom and two oxygen atoms, the molar mass of carbon dioxide (IV) is:

Molar Mass (CO2) = (1 * 12.01 g/mol) + (2 * 16.00 g/mol) = 44.01 g/mol

Now, we can calculate the amount of substance (n) in 33g of carbon dioxide (IV) using the formula mentioned earlier:

n = 33g / 44.01 g/mol

Calculating this, we get:

n ≈ 0.75 mol

Therefore, there are approximately 0.75 moles of carbon dioxide (IV) in 33g of the compound.

Please note that the calculations provided here are based on the given information and the molar mass of carbon dioxide (IV).
