A sample of crude oil contains 3.23 mM naphthalene, 13.4 mM methylnaphthalene, 23.4 mM dimethylnaphthalene, and 14.8 mM trimethylnaphthalene. What is the total number of moles of all naphthalene compounds combined in 100.0 mL of the oil?
Homework Answers
Volume of oil = 100 ml = 0.1 L
Total number of moles of all the naphthalene compounds= concentration x volume
= (3.23 mM + 13.4 mM + 23.4 mM + 14.8mM) x 0.1 L
= 54.83 mM x 0.1 L = 5.483 mmoles = 5.483 x 10^-3 moles
