Question

Number of H+ ions in 100ml of 0.001M H2SO4 is

Answer 1

Hey mate,..

here's your answer,...

Meq of H2SO4=100×0.001=0.1H2SO4=100×0.001=0.1

1000mM of H2SO4=2 mole H+

∴ 0.1mM H2SO4=2×0.1×6×10^23/1000
H2SO4
=2×0.1×6×10^23/1000

⇒1.2×10^20

hope it helps you,...
pls mark me as the brainliest,....

Answer 2

Answer:

The correct answer to this question is $1.2$ × $10^{20}$

Explanation:

Given - Number of H+ ions in 100ml of 0.001M $H_{2}SO_{4}$

To Find - Write the number of H+ ions in 100ml of 0.001M $H_{2}SO_{4}$ .

The hydronium ion is represented by the formula H+, which is alternatively written as H3O+. The quantity of hydrogen ions in a water solution is used to determine a substance's acidity; the greater the hydrogen ion concentration, the more acidic the solution and the lower the pH.

According to the question,

$H_{2}SO_{4}$  = 100 × 0.001 = 0.1

And,

1000mm $H_{2}SO_{4}$ = $2$ mole of $H^{+}$

Therefore, 0.1mM $H_{2}SO_{4}$ = 2 × 0.1 × 6 × $10^{23}$ / 1000

= $1.2$ × $10^{20}$
