Número de moles = concentración * volumen
concentración = 2 M
volumen = 875 ml
Número de lunares = 2 * 875/1000
Número de lunares = 1,75 moles
Número de moles = masa / masa molar
masa molar de hidróxido de calcio = 74.093 g / mol
1,75 moles = masa / 74,093 g / mol
masa = 1,75 moles * 74,093 g / mol
masa = 129,66 g
