How many grams of sulfur (S8) must be dissolved in 100.0 naphthalene (C10H8) to make a 0.13 solution?
answer in grams.
You didn't use any units. I assume 0.13 is molar and I assume 100 is mL (which in the equation below will be 0.1 L)
M = moles/L.
You have M and L. solve for moles.
Then moles = grams/molar mass. Solve for grams.
