Question

Какова масса 5 моль углекислого газа?

Answer 1

m(CO2) = ню(CO2)*Mr(CO2)

Mr  = 12+16*2 = 44

m(CO2) = 44*5 = 220 грамм

Answer 2

сначала ты считаешь массу самого вещества
С=12,О2=32(16*2)
потом  складываешь
12+32=44
далее
ты должна массу умножить на 5 моль
получается 5*44=220

Answer 3

Calculating the Mass of 5 Moles of Carbon Dioxide

To calculate the mass of 5 moles of carbon dioxide (CO2), we can use the molar mass of carbon dioxide, which is the sum of the atomic masses of the elements it contains.

The molar mass of carbon dioxide (CO2) can be calculated as follows: - Carbon (C) has an atomic mass of approximately 12.01 g/mol. - Oxygen (O) has an atomic mass of approximately 16.00 g/mol.

Using this information, we can calculate the molar mass of carbon dioxide as follows: - Molar mass of CO2 = (12.01 g/mol for C) + 2*(16.00 g/mol for O) - Molar mass of CO2 = 12.01 g/mol + 32.00 g/mol - Molar mass of CO2 = 44.01 g/mol

Now, to find the mass of 5 moles of carbon dioxide, we can use the following formula: - Mass = Number of moles * Molar mass

Substituting the values: - Mass = 5 moles * 44.01 g/mol - Mass = 220.05 grams

The mass of 5 moles of carbon dioxide is approximately 220.05 grams.
