Question

Calculate the mass of co2 wch contains the same no. Of molecules as are contained in 40g of oxygen

Answer 1

Hi.

Here is your answer---------------

Given----

For oxygen,

Mass of the oxygen = 40 grams.
Molecular mass of the oxygen = 32 grams.

Thus, number of molecules =( mass/ molecular mass) x Avogadro's number.
                                            = (40/32) x Avogadro's number.

Molecular mass of carbon dioxide = 44 grams.
Thus, number of molecules = (mass/44) x Avogadro's number.

According to the question,

        Number of molecules of CO2 = Number of moecules of O2
Therefore,  Mass/44 = 40/32
                        Mass of CO2 = 55 grams.

Thus, mass of carbon dioxide (CO2) = 55 grams.
