Question =》
Which of the following pair of element represent a mole of ratio 1 : 1 ?
Answer
No of moles in 12g of mg = 12/24= 1/2 = 0.5 mole
No of moles in 6g of carbon = 6/12=1/2=0.5 mole
......Ratio......
= 0.5/0.5 = 1:1
So , option B is correct ✔
Option B is correct ✔

Question =》
which of the following correctly represent 360 gram of water?
Answer
The molar mass of water is 18g/mol
360g of water corresponds to 360g / 18g/mol= 20mol
It is also equal to 20mol× 6.025×10²³ molecules/mol= 1.2044× 10²⁵molecules
So, Option D is correct ✔

Question =》
if 32 gram of sulphur has X atoms then the number of atoms in 32 gram of Oxygen will be
Answer
Atomic mass of sulphur is 32g/mol
Therefore, Number of moles of sulphur is 1 and it contains 6.022×10²³atoms.
In 32g of oxygen contains 2 moles and atomic mass of oxygen is 16g/mol.
And hence it will contain 2× 6.022×10²³atoms
So, Option B is correct
