If a tablet of acetaminophen, C8H9NO2, weighs 324 mg, how many moles are there in the tablet? If a tablet of acetaminophen, C8H9
Gnoma [55]

Answer:

2.14*10^{-3} mol

Explanation:

number of moles of C8H9NO2 = \frac{mass}{molar mass}=\frac{324*10^{-3} g}{151.163g/mol}=2.14*10^{-3}mol

The trick is to remember to convert milligrams to grams because molar mass is normally presented in grams per mole

How many hydrogen atoms are in 8.80 mol of ammonium sulfide
vladimir1956 [14]
Assuming that the ammonium sulfide formula is (NH4)2S then you can see that there are 2 nitrogen, 8 hydrogen and 2 sulfur atoms for every ammonium sulfide. If the amount of ammonium sulfide is 8.9 moles, then the number of hydrogen atoms should be: 8/1 * 8.9 mol= 71.2 moles
