Which of the following species has highest mass?
Options
- A1 ~g atom of carbon
- B3.011 10²³ atoms of oxygen
- C10 ~mL of water at room temperature
- D1 2 mole of CH ₄
Correct answer
A. 1 ~g atom of carbon
Step-by-step solution
Mass of 1 ~g atom of carbon =12 ~g 3.011 10²³ atoms of oxygen =0.5 ~mol atom aligned & =0.5 16=5 ~g & 10 ml H ₂ O =10 ~g H ₂ O & 1 2 ~mol CH ₄= 1 2 16=8 ~g aligned
