Allyl sulfide gives garlic its characteristic odor. Give the mass and number of carbon atoms.

Question

a) The mass in grams of 2.62 mol of allyl sulfide. Answer in scientific notation.

b) The number of carbon atoms in 72.8 g of allyl sulfide. Answer in scientific notation.

Answer 1

Here is an image of allyl sulfide.

Count up the C, H, and S to determine the molecular formula.

From the formula, calculate the molar mass (g/mol).

(a) Use the molar mass to convert 2.62 mol of allyl sulfide to grams;

(b) Use the molar mass to convert 72.8 g of allyl sulfide to moles .....

then determine the moles of carbon atoms per mole allyl sulfide .....

then use Avogadro's number 6.022 x 10^23 atoms per mole to determine the number of carbon atoms
