WebThe mass of K is provided, and the corresponding amount of K in moles is requested. Referring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable “ballpark” estimate of the number of moles would be ... WebSo here In 31.30 g or formally hide, how many hydrogen do we have for the mass of hydrogen? So let us assume it is X. So we will calculate the value of X by doing the cross multiplication. 31.30 multiplied by two divided by 30. So from here we get the master of hydration as 2.087 g. So now we've got the mass of hydrogen Adams.
