What is the mass of 8.12 x 10^23 molecules of co2

The mass of molecules of carbon-di-oxide is 59.319 grams.

Avogadro number has been able to give the number of molecules in a mole of a compound.

From the Avogadro number, the moles of Carbon-di-oxide in molecules will be:

Moles of Carbon di-oxide =

Avogadro number = 6.023

number of molecules of carbon-di-oxide =

Moles of carbon dioxide =

Moles of carbon-di-oxide = 1.34 moles.

The molar mass of the substance can be defined as the mass of 1 mole of a substance.

The molar mass of Carbon-di-oxide = 44 g/mole

Mass of 1 mole of Carbon-di-oxide = 44 g

Mass of 1.34 moles of Carbon-di-oxide = 59.319 grams.

The mass of molecules of carbon-di-oxide is 59.319 grams.

Explanation:

Mole = no. Molecules/6.02×10^23

Mole = (8.12×10^23)/(6.02×10^23)

Mole = 1.35mole

Molar mass of CO2 = 12+ 2(16)

Molar mass= 12 + 32= 44g/mol

Mole = mass/molar mass

Mass = Mole × molar mass

Mass = 1.35× 44

Mass= 59.35g

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
