Answer:
The answer is 916.67 g
Explanation:
48.0 wt% NaOH means that there are 48 g of NaOH in 100 g of solution. With this information and the molecular weight of NaOH (40 g/mol), we can calculate the number of mol there are in 100 g of this solution:
x 
= 0.012 mol NaOH/100 g solution
Finally, we need 0.11 mol in 1 liter of solution to obtain a 0.11 M NaOH solution.
0.012 mol NaOH ------------ 100 g solution
0.11 mol NaOH------------------------- X
X= 0.11 mol NaOH x 100 g/ 0.012 mol NaOH= 916.67 g
We have to weigh 916.67 g of 48.0%wt NaOH and dilute it in a final volume of 1 L of water to obtain a 0.11 M NaOH solution.
Answer:
OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)
Explanation:
The net ionic equation is a way yo write a chemical equation that list only the species that are involved in the reaction.
For the reaction:
NaOH(aq) + NH₄Br(aq) → NaBr(aq) + NH₃(g) + H₂O(l)
Ionic equation is:
Na⁺(aq) + OH⁻(aq) + NH₄⁺(aq) + Br⁻(aq) → Na⁺(aq) + Br⁻(aq) + NH₃(g) + H₂O(l)
<em>-Ions comes from the species that are in aqueous phase-</em>
And net ionic equation is:
<em>OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)</em>

Answer:
Explanation:
In one mole of liquid HF , no of molecules is 6.02 x 10²³.
Each molecule forms two hydrogen bonds on an average so no of hydrogen bonds per mol ih HF is
2 x 6.02 x 10²³.
= 12.04 x 10²³ .
In water no of hydrogen bonds per molecule of water is 4 . So in one mole of water no of hydrogen bonds is
4 x 6.02 x 10²³.
= 24.08 x 10²³ .
You'll need the specific heat capacity of aluminium to solve this question.
H=(0.005)(37-22)(specific heat capacity of aluminium)
