Conociendo el volumen de la solución y la masa del soluto y su masa molar, ¿qué concentración es posible determinar
NISA [10]

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

CO2(g) + 2 LiOH(s) → Li CO3(aq) + H2O
Vadim26 [7]

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.
