MCQ
Which of the following has the highest mass
  • A
    $1\,g-$ atom of phosphorous
  • B
    $2\,moles$ of water
  • ✓
    $22.4\,L$ of $CO_2$ gas at $NTP$
  • D
    $6.02 \times 10^{23}$ atoms of sulphur
✓

Answer

Correct option: C.
$22.4\,L$ of $CO_2$ gas at $NTP$
c
$2\,moles$ of water $= 36\;g$

$22.4\,L$ of $CO_2$ gas at $NTP\;=44\;g$ 

$6.02 \times 10^{23}$ atoms of sulphur $=32\;g$
