18 g of water have the same number of atoms as 48 g of ozone.

Question

Quizplus · Accepted Answer

Both 18 g of water (H2O) and 48 g of ozone (O3) contain 1 mole each, based on their molar masses (18 g/mol for water and 48 g/mol for ozone). Since 1 mole of any substance contains Avogadro's number of molecules (6.022 x 10^23), and each molecule of water contains 3 atoms (2 hydrogen and 1 oxygen) and each molecule of ozone contains 3 oxygen atoms, both samples contain the same number of atoms when considering the total atoms present in the moles of each substance.
