How many molecules are in 3.0 moles of carbon dioxide (co2)?
a. 1.8 x 10 24
c. 2.0 x 1024
b. 2.4 x 1023
d. 2.6 x 1024

Mole of a substance is defined as the molecular weight in grams of that substance. According to Avogadro’s number, one mole of any substance is equal to 6.023x10^23 units. The units can be atoms, formula units, molecule, ions, electrons. In this problem, there are three moles of CO2. Since the Avogadro’s number states that one mole of ANY substance is equal to 6.023x10^23 units, you can multiply 6.023x10^23 units by three. You will get 1.80x10^24 units. Change the units into molecules and you will get 1.80x10^24 molecules. The answer is a.

Fine out you self hx

A1 a 2 a 3 ooh lol i think that's it
