Question

Weight of 6.022x10% formula units of Na2CO3. will (in g)​

Answer 1

Answer:

Number of molecules = 6.02 X 1023 molecules

We know that

6.02 X 1023 molecules equals 1 mole.

Find out

Mass of CO2

Formula

No of moles = Given mass/molar mass

The molar mass of CO2 is 44 gram/mol.

Solution

Mass of CO2= no of moles × molar mass

Substituting the values in the formula we get

Mass of CO2 = 1 mol × 44

Mass of CO2 = 44 grams

Hence, Mass of CO2 = 44 grams
