Use the numerical constant shown below to determine if the statement is true or false. Avogadro’s number = 6.022 x 1023 particles/mole{“version”:”1.1″,”math”:”6.022 x 1023 particles/mole”} The chemical formula for a molecule of caffeine is C8H10N4O2{“version”:”1.1″,”math”:”C8H10N4O2″}. The molecular weight of caffeine is 194.19 g/mole. Based on this information, the number of oxygen atoms in 95 milligrams of caffeine is equal to 5.89 x 1020 atoms{“version”:”1.1″,”math”:”5.89 x 1020 atoms”} .
