The PH of a solution of Hcl is 2.find out the amount of acid present in a litre of the solution

Scrat [10]

Answer:

The solution is 10^-2 or 0.01M in HCl.

Explanation:

meaning of pH is "power of hydrogen".

what is the molar concentration of a HCl solution with pH=2?

Let say pH=2

[H+]=10^-2M

HCL is a strong acid that dissociates completely:

[H+]=[HCL]

Therefore solution is 10^-2 or 0.01M in HCL.

What is the total mass of Hydrogen in each of the molecules?

frutty [35]

Explanation:

a) In 1 mole of methane there are 4 moles of hydrogen atom

Atomic mass of 1 mole of hydrogen atom = 1 g

Mass of hydrogen in 1 mole of methane = 4 × 1 g = 4 g

b) In 1 mole of chloroform there are 1 mole of hydrogen atom

Atomic mass of 1 mole of hydrogen atom = 1 g

Mass of hydrogen in 1 mole of methane = 1× 1 g = 1 g

c) In 1 mole of $C_{12}H_{10}O_{16}$ there are 10 moles of hydrogen atom

Atomic mass of 1 mole of hydrogen atom = 1 g

Mass of hydrogen in 1 mole of $C_{12}H_{10}O_{16}$ = 10 × 1 g = 10 g

d)In 1 mole of $CH_3CH_2CH_2CH_2CH_3$ there are 12 moles of hydrogen atom.

$CH_3CH_2CH_2CH_2CH_3=C_5H_{12}$

Atomic mass of 1 mole of hydrogen atom = 1 g

Mass of hydrogen in 1 mole of $CH_3CH_2CH_2CH_2CH_3$ = 12 × 1 g = 12 g
