There are 5.66 moles of hydrogen in the sample of talc(hydrated magnesium silicate).
Given,
Talc formula is
moles of magnesium = 8.5 moles
The stoichiometry of magnesium and hydrogen is 3 : 2,
So 3 moles of magnesium is equivalent to 2 moles of hydrogen.
Then 8.5 moles of magnesium is equivalent to =5.6666 moles
<h3>Talc </h3>
Talc(hydrated magnesium silicate), often known as talcum, is a type of clay mineral made up of hydrated magnesium silicate, having the formula Mg3Si4O10(OH)2. Baby powder is made of powdered talc, frequently mixed with corn starch. This mineral serves as a lubricant and thickening agent. It serves as a component in paint, pottery, and roofing materials. It serves as a key component in many cosmetics. It can be found as foliated to fibrous aggregates and in a remarkably uncommon crystal form. It is foliated with a two-dimensional platy form, has a flawless basal cleavage, and an irregular flat fracture.
Talc(hydrated magnesium silicate), the softest mineral, is assigned a value of 1 on the Mohs scale of mineral hardness, which is based on scratch hardness comparisons.
