How many moles are there in 987 grams of Ra(OH)2? id also love to know the simplest equation for converting moles --> so i could practice on my own :)

Mole = [tex] \frac{mass}{molar mass} [/tex]

Mass of Radium Hydroxide = 987g
Molar Mass of [tex]Ra(OH) _{2} [/tex] = ((226) + (2 * 16) + (2 * 1))
                                            =  260 g / mol

∴  Moles of [tex]Ra(OH) _{2} [/tex] = [tex] \frac{987 g }{ 260 g / mol } [/tex]
                                            = 3.796 mols
