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
It can be disproven by philosophy and religion.

Explanation:
Answer:
958 g is the mass of LiOH that can react with all the CO₂
Explanation:
CO₂(g) + 2 LiOH(s) → Li₂CO₃(aq) + H₂O
We think in the reaction:
1 mol of carbon dioxide can react with 2 moles of lithium hydroxide.
First of all, we convert the mass of our reactant to mol:
880 g . 1mol /44g = 20 moles
As ratio is 1:2, 20 moles of CO₂ will react with 40 moles of LiOH.
Let's determine the mass:
40 mol . 23.95 g /1mol = 958 g
It depends on what the reaction is. Usually H2O is neutral. If in the reaction, it accepts proton(H+), it is base. If it donors the proton(H+), it is acid. So it based on what reaction it is.
