1. (UFJF) Um estudante recolheu 1 litro de soluçåo saturada de sulfato de cobre e, apos deixar o recipiente por uma semana na temperatura ambiente, verificou a presença de cristais de sulfalo de cobre e um volume de soluçäo final de 700 mL . Sabendo-se que a solubilidade do sulfato de cobre é de 22.3 gem 100 mL de água, nessa temperatura, qual a massa (em gramas) de sulfato de cobre precipitada?
