Uma concentra\u00e7\u00e3o de 1 mol\/L significa que cada litro de solu\u00e7\u00e3o cont\u00e9m um mol da subst\u00e2ncia especificada \u2014 e n\u00e3o que um mol foi adicionado a um litro de solvente. O que importa \u00e9 o volume final da solu\u00e7\u00e3o.<\/p>\n<p>Todas as unidades deste conversor expressam o mesmo tipo de grandeza: quantidade de subst\u00e2ncia por volume. Converter entre elas altera o n\u00famero e a sua unidade, n\u00e3o a concentra\u00e7\u00e3o f\u00edsica. Um resultado num\u00e9rico maior n\u00e3o significa que a solu\u00e7\u00e3o ficou mais concentrada; pode simplesmente refletir uma unidade menor, como mmol em vez de mol.<\/p>\n<p>Estas convers\u00f5es s\u00e3o \u00fateis para comparar medi\u00e7\u00f5es de laborat\u00f3rio, ler dados reportados em unidades do SI ou transferir uma concentra\u00e7\u00e3o para um c\u00e1lculo. Se conhece a massa de uma subst\u00e2ncia em vez da quantidade em moles, use primeiro a <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/mols-e-gramas\/\">calculadora de Mols e Gramas<\/a>.
