We first write the equation for the reaction as follows.

Mg(s) + 2H2O (l) —> Mg(OH)2 (aq) + H2 (g)

Molar mass of Magnesium is 24 g

The number of Magnesium moles is thus :

24/24 = 1 mole

The mole ratio of magnesium to Hydrogen is 1 : 1

Therefore 1 mole of Hydrogen gas is liberated.

The answer is thus 1 mole.

Answer:

The mole of H2 liberated is 1 mole

Explanation:

A mole is described as the quantity of a substance that includes precisely 6.02214076 X1023 simple entities of the given substance. A mole of a substance is mentioned the mass of a substance containing the equal range of essential devices as there are atoms in precisely 12.000 g of 12C.

Number of moles method is. Number of moles = Mass of substance / Mass of 1 mole. Number of moles = 95 / 86.94.

One mole of a substance has the equal mass in grams that one atom or molecule has in atomic mass devices

We first write the equation for the response as follows.

Mg(s) + 2H2O (l) —> Mg(OH)2 (aq) + H2 (g)

Molar mass of Magnesium is 24 g

The range of Magnesium moles is :

24/24 = 1 mole

The mole ratio of magnesium to Hydrogen is 1 : 1

Therefore 1 mole of Hydrogen fueloline is liberated.

The solution is  1 mole.
