Question

calculate the mass of the following two moles of carbon dioxide and 6.022 ×10^23 molecules of carbon dioxide​

Answer 1

Answer:

Explanation:

Given:

no of moles = 2

no of molecules = 6.02 * 10^23 molecules

To find out:

Mass of 2 moles of CO2=?

Solution:

Formula being used here:

No of Moles= given mass/molar mass

Molar mass of CO2 is  44 g/mol

So,

Mass= no of moles * no of moles

Putting values:

Mass=  2 * 44

Mass= 88 g

So,the mass of two moles of CO2 is 88 g

We know that 6.02*10^23 molecules equals one mole.

From here,we can easily find the mass of 6.02*10^23 molecules of CO2.

It is known:

No of moles= given mass/molar mass

Rearranging it :

Mass of CO2 = no of moles * molar mass

                       = 1 mol * 44 g/mol

                       =44 grams.

So,the mass of 1 mole or 6.02*10^23 molecules of CO2 is 44 grams.

HAVE A GREAT DAY MATE :)
