Question

In 0.1 M, 100 mL solution of HCl, total number of H+ ions are :

Answer 1

Answer:

0.01 mol or 10^-2 mol

Explanation:

Molarity= no. of moles / total volume of solution.

=> 0.1= n/100×10^-3

=> n= 0.01 mol or 10^-2 mole

Answer 2

Answer:

=6.023*10^21 (H+ ions)

I am not really sure of my answer so please cross check with your teacher

Explanation:

MOLARITY =(n*1000/V)

n = moles of HCL

V = Volume of HCL added

N= 0.1*100/1000

=0.01

1 mole of HCL contains = 6.023*10^23(H+ ions)

S0, 0.01 mole of HCL contains

6.023*10^23 * 0.1

=6.023*10^21 (H+ ions)
