Question

How many times an atom of sulphur is heavier than an atom of carbon

Answer 1

The sulphur is larger the carbon atom by 2.67 times.

Explanation:

To calculate this ratio, we use the atomic mass of the given atoms.  We know that the atomic weight of the carbon atom is 12 amu and that of one atom of sulphur is 32 amu.

Then, the ratio of atomic weight is sulphur to carbon = 32:12 = 8:3

That is,

$\frac{8}{3}=2.67$

Alternatively, we can also make use of the mole concept. The number of atoms (N) can be calculated by using the given mass and atomic or molecular mass of the elements.

$N = \frac{m}{M}$

Where,

N is the number of atoms

m is the mass of the element  

M is the molecular mass of the element.

We know that we have to calculate the m i.e., mass of 1 atom.

So, for carbon where M = 12

$1=\frac{m}{12}$

i.e., mass of 1 carbon atom = 12 amu

For sulphur where M = 32

$1=\frac{m}{32}$

$m=32 \ \mathrm{amu}$

Then, the ratio of mass of sulphur to carbon

$\Rightarrow 32 : 12 = 8 : 3$

$\frac{8}{3}=2.67$

Answer 2

Answer:

the correct answer is 8/3 times..
