Answer to Question #140496 in General Chemistry for Abigail

Question

A mole of H+ (1 mole H+) contains _______ H+ ions.
1 mole of H+ contains____________ mol of positive charges (+).
1 mole of Ca2+ contains_______Ca 2+ ions.
1 mole of Ca2+ contains___________mole (+).
1 mole of Al3+ contains___________mole (+).

Answer 1

We know,

1 mole of any substance contain N_A number of particle.

Where, N_A = 6.023×10²³

A mole of H+ (1 mole H+) contains

= 6.023×10²³ H+ ions

Each H+ ion has one (+) positive change.

So,

1 mole of H+ contains 1 mole of positive charges (+).

Similarly,

1 mole of Ca2+ contains 6.023×10²³ Ca2+ ions.

Each of Ca2+ ion has 2 (two) positive change

1 mole of Ca2+ containn 2 mole (+).

Each Al3+ ion has 3 (three) positive change

1 mole of Al3+ contains 3 mole (+).
