Question

Q. Number of water molecules in 1 mL of water at S.T. P is equal to
[A] 6.02 x 10^23 [B] 1.0 x 10^19
[C] 2.69 x 10^19 [D] 3.73 x 10^19​

Answer 1

Answer:

c

0.001 \ 22.414 = 0.000044614

Explanation:

moles=volume(dm3)/volume(STP)

0.001 \ 22.414 = 0.0000446

molecules = moles x avogadros number

molecules=0.0000446×6.02×10*23 =2.69×10*19
