WebPara realizar o cálculo do Kps, devemos realizar os seguintes passos: 1º Passo: Calcular a massa molar do sal. Para determinar a massa molar do sal, basta multiplicar a massa do elemento pela sua quantidade de átomos na fórmula e, em seguida, somar todos os resultados: M1 = 1.137 + 1.32 + 4.16. M1 = 137 + 32 + 64.
