How many hydrogen atoms are present in 1 mg of aspartame?

Aspartame has the chemical formula C14H18N2O5. In 1 molecule of aspartame, there are 18 hydrogen atoms. To find the number of hydrogen atoms in 1 mg of aspartame, you first need to calculate the number of molecules in 1 mg (0.001 g) by dividing by its molar mass (approximately 294.3 g/mol). This results in around 0.0034 moles of aspartame, which corresponds to approximately 7.5 × 10²² hydrogen atoms in 1 mg.
