An analytical chemist has determined by measurements that there are 8. 5 moles of magnesium in a sample of talc. how many moles of hydrogen are in the sample?

Sagot :

The moles of hydrogen in the talc sample are 5.67 moles.

Talc are the hydrous silicate minerals. The chemical formula of talc is Mg₃Si₄O₁₀(OH)₂.

From the formula it can be determined that there are: 3 moles of Mg, 4 moles of Si, 12 moles of O and 2 moles of H.

Moles are a type of SI unit of measurement of the amount of substance.

According to the question, magnesium = 8.5 moles

Also, 3 moles of Mg = 2 moles of H

Therefore, moles of H = 8.5 moles × (2 moles H / 3 moles Mg)

                 moles of H = 5.67 moles
