Question

The compound responsible for the characteristic smell of garlic is allicin, C 6H 10OS 2. The mass of 1.00 mol of allicin, rounded to the nearest integer, is ________ g. 34 162 86 61 19

Answer 1

Answer: The answer is 162g.

Explanation: To calculate the mass of a molecule, you have to find the molar mass of each element of the molecule.

Molar mass of C = 12g/mol

Molar mass of H = 1g/mol

Molar mass of O = 16g/mol

Molar mass of S = 32g/mol

From the allicin's formula, there are:

6 C = 6.12 = 72

10 H = 10.1 = 10

1 O = 1.16 = 16

2 S = 2.32 = 64

Adding them up:

C6H10OS2 = 72+10+16+64 = 162g/mol.

As it is requested 1 mol of allicin, it has 162g.

Answer 2

Answer:

162 g/mol

Explanation:

This problem requires us to calculate the molar mass of allicin, grs/mol. So with the atomic weights of the atoms in this compound, the molar mass will be the sum of the atomic weight multiplied by the number of atoms in the formula.

atomic weights ( g/mol )

C : 12.01 g/mol

H :  1.00 g/mol

O: 16.00 g/mol

S : 32.06 g/mol

Molar mass C₆H₁₀Os₂ (g/mol ) = 6 x 12.01 + 10 x 1.00 + 1 x 16 +2 x 32.06

                                                  = 162 g/mol  (rounded to the nearest integer)
