Do you think one mole of the different substances has the same amount?​
vagabundo [1.1K]

It's because of Avagadro's number.

  • It is known as Avagadro's constant too.
  • It states that at constant temperature one mole of any substance contain same number of atoms i.e n no of atoms

where

\\ \sf\longmapsto n=6.022\times 10^{23}

W(OH)2 + 2 HCl → WCl2 + 2 H2O
Afina-wow [57]

The amount of W(OH)2 needed would be 448.126 g

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

W(OH)2 + 2 HCl → WCl2 + 2 H2O

The mole ratio of W(OH)2 to HCl is 1:2

Mole of 150g HCl = 150/36.461

                                 = 4.11 moles

Equivalent mole of W(OH)2 = 4.11/2

                                           = 2.06 moles

Mass of 2.06 moles W(OH)2 = 2.06 x 217.855

                                                = 448.188g
