If there are 0.20 moles in 8.9 grams of CO2, what is the number of CO2 molecules? Use this equation to find the answer: Moles in sample (mol) x Avogadro's number (6.022 x 1023) = Number of sample molecules 0.20 x 1023 1.2 x 1023 8.9 x 1023 20 x 1023
How does Avogadro's number relate to the atomic mass and moles of an element? Avogadro's number can be used to convert the atomic mass of an element to the mass of one mole of that element The mass of one mole of an element can be used to convert the atomic mass of that element to Avogadro's number. Avogadro's number is not related to the atomic mass of an element or the mass of a mole of that element. The...
