Question

What is meant by one mole? Determine the number of
mole present in 22gm Coz.​

Answer 1

Answer:

The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules) in a certain mass of a given substance. Avogadro's number is an absolute number: there are 6.022×1023 elementary entities in 1 mole. ... The mass of one mole of a substance is equal to that substance's molecular weight.

For our problem, this means that one mole of CO2 has a mass of 44.01 grams. So 22 grams divided by 44.01 grams is roughly 0.5 moles of CO2.
