Question

Match List I with List II

LIST I	LIST II
A. 88 g of CO2	I. 2 mol
B. 6.023 × 1023 molecules of H2O	II. 1 mol
C. 96 g of O2	III. 6.023 × 1023 molecules
D. 1 mol of any gas	IV. 3 mol

Choose the correct answer from the options given below:

• A. (A)- (I), (B)- (II), (C)- (IV), (D)- (III)
• B. (A)- (III), (B)- (II), (C)- (I), (D)- (IV)
• C. (A)- (II), (B)- (I), (C)- (III), (D)- (IV)
• D. (A)- (II), (B)- (III), (C)- (I), (D)- (IV)

Hint:

To convert mass into moles, use the molar mass of the substance, and for molecules, use Avogadro’s number to convert between molecules and moles.

Answer 1

The Correct Option is A

88 g of CO\(_2\) corresponds to 2 moles. \( 6.023 \times 10^{23} \) molecules of H\(_2\)O is 1 mole. 96 g of O\(_2\) corresponds to 3 moles. 1 mol of any gas occupies 22.4 L at STP, which is \( 6.023 \times 10^{23} \) molecules.
