Question

calculate the mass of 2.5 mole of co2​

Answer 1

Answer:

co2 = 12+2(16)= 44

6.022×10_22/2.5

Answer 2

Given,

The given chemical compound is carbon dioxide (CO₂).

Amount of the given chemical compound is 2.5 mole.

To find,

The mass of the given amount of carbon dioxide.

Solution,

We can simply solve this numerical problem, by using the following method.

First of all we have to calculate the molar mass of the carbon dioxide.

Molar mass of CO₂ = 12 + (2×16) = 12+32 = 44 g/mol

Now,

Mass of the given amount of chemical compound = Number of moles of given chemical compound × Molar mass of the given chemical compound

Mass of the given amount of chemical compound = (44×2.5) = 110 grams

Hence, the mass of 2.5 mole of CO₂ is 110 grams.
