Question

Chemistry question kindly give the answer.

Answer 1

the option c is correct

Answer 2

Answer:

B

Explanation:

It is given that volume of water =18ml

And density = d= 1g/ml

And density = mass/volume

Therefore, mass of water = density*volume

Hence, mass =1g/ml*18ml

Mass = 18g

Molar mass of water=2*1+16=18g/mol

Now, no. of moles = mass/molar mass

Hence,no. of moles =18/18=1mol

Now,no. of electrons =mole*avagadro no.*entities

Hence, no. of electrons =1*6.022*10^23*10

6.022*10^24.
