Answer:
Conociendo el volumen de solución, masa de soluto y su masa molar, es posible determinar: B) Concentración molar
La molaridad es la relación entre el número de moles de soluto y los litros de solución. Más:
M = No moles de solución de soluto / volumen (L)
Y a su vez los moles de soluto se encuentran por:
No moles de soluto = masa soluto / masa molar soluto
<span>I think the correct answer is A. A
buffer is a substance that resists small change in the acidity of a solution
when an acid or base is added to the solution. Usually, a buffer involves a
weak acid or a weak alkali and one of its salt.</span>
Answer:
The Bronsted-Lowery acid is H2O
The Bronsted-Lowery base is CO3
The conjugate acid is HCO3
The conjugate base is OH
Explanation:
Molocules that lose a hydrogen in a reaction act as an acid, and those that recieve one act as a base.
