Question

N(co2)=2мольm=?m=n*M

Answer 1

M = 44

m = 2 * 44 = 88

Answer 2

To calculate the mass (m) of 2 moles of carbon dioxide (CO2), you need to know the molar mass (M) of CO2.

The molar mass of CO2 can be calculated by adding up the atomic masses of its constituent elements, which are carbon (C) and oxygen (O).

The atomic masses are approximately:

• Carbon (C) atomic mass ≈ 12.01 g/mol
• Oxygen (O) atomic mass ≈ 16.00 g/mol

Now, to find the molar mass of CO2: M(CO2) = (2 * M(C)) + (2 * M(O)) M(CO2) = (2 * 12.01 g/mol) + (2 * 16.00 g/mol) M(CO2) = 24.02 g/mol + 32.00 g/mol M(CO2) = 56.02 g/mol

Now, you can use the formula: m = n * M

where: n = 2 moles (number of moles of CO2) M = 56.02 g/mol (molar mass of CO2)

m = 2 moles * 56.02 g/mol ≈ 112.04 g

So, the mass of 2 moles of carbon dioxide (CO2) is approximately 112.04 grams.
