NEET Chemistry Question (2024) — Solution
Options
- A. 14 g of N _2
- B. 18 g of H _2 O
- C. 16 g of CO
- D. 28 g of N _2
Answer
A. 14 g of N _2
Step-by-step solution
Number of moles of H _2= 1 2 =0.5 Number of molecules of H _2=0.5 ~N _ A . (1) Number of moles of N _2= 14 28 =0.5 Number of molecules of N _2=0.5 ~N _ A (2) Number of moles of H _2 O = 18 18 =1 Number of molecules of H _2 O =1 N _ A = N _ A (3) Number of moles of CO = 16 28 = 4 7 Number of molecules of CO = 4 7 ~N _ A (4) Number of moles of N _2= 28 28 =1 Number of molecules of N _2=1 N _ A = N _ A
