Question

how many molecules approximate do you expect to be present in One drop of water with 0.05 cc volume ​

Answer 1

Answer:

Thus, the number of moles in 0.05 mL water = 0.05/18 = 0.00278 moles. Now, 1 mole of anything contains 6.023 x 10 atoms, molecules, elementary units, whatever! So, 0.00278 moles of water will have 0.00278 * 6.023 * 10 molecules of water. This is, 1.674 x 10 molecules.

Answer 2

Answer:

Explanation:

You know that density of water is 1gm/ml

And by this 1gm=1ml

And 1cc=1ml

And 0.05cc is 0.05 ml

By above

0.05 ml has 0.05 g

And moles=0.05/18=0.00278

And molecules = moles×avagadro number

=0.00278Na
