Chemistry problem finding molar mass of allicin...?

Question

The molecular formula of allicin, the compound responsible for the characteristic smell of garlic, is C6H10OS2.

a) What is the molar mass of allicin?

b) How many moles of allicin are present in 5.00 mg of this substance?

d)how many S atoms are present in 5.00 mg of allicin?

Answer 1

I looked it up.  It gave me this website.  Please check my source.  OK?  

Answer 2

A. (molar mass of Carbon * 6) + (mm of Hydrogen * 10) + (mm of Oxygen * 1) + (mm of Sulfur * 2) = mm of C6H10OS2

SO....

(12.01 * 6) + (1.01 * 10) + (16.00 * 1) + (32.07 * 2) = 162.3g C6H10OS2 per mole

all the molar masses came from the Table of Elements.

B. (.005 g / 1 ) * ( 1 mole / 162.3 g) = 0.005/162.3 = .0000308 moles

Answer 3

a) molar mass of carbon x6 plus molar mass of Hydrogen( 10 grams) plus molar mass of oxygen plus molar mass of sulfur x 2.

b) 5.00 mg (convert to grams)/molar mass of allicin

d) answer from b/ molar mass of S

   Then that answer multiplied by  6.o2 x10^23 atoms

Answer 4

Use your table of elements and add up the mass.
