Actually you have now a roport of 4:96 water to acid . All you have to do is add water to bring the raport to 37 acid and 63 water.
You need to have 0.5L mixture so
you have to have 18.5acid and the rest water 31.5
so for 18.5 acid you need to add 192.7 ml 96% acid and the rest water
You can predict its acidity (pH).
The formula for pH is: pH = log { 1 / [H+] } = log { 1 / (1*10^-12) }
=> pH = log {10^12} = 12.
Remember that acids have pH between 1 and less than 7 and basic compounds have pH greater than 7 and less than 14.
So, you can predict that this product is a base (alkaline).
Answer:
a. Al2S3.
Explanation:
Molar mass of Al = 26.98
Molar mass of S = 32.06.
Ratio of AL:S is 1 : 1.78
Dividing by the moles we get:
0.0371 : 0.0555
= 1 : 1.5
So its Al2S3.
Answer : The molality of a solution is, 0.387 mol/kg
Explanation : Given,
Mass of solute (glycine) = 100.7 g
Mass of solvent (water) = 3.466 kg
Molar mass of glycine = 75.1 g/mole
Formula used :
Now put all the given values in this formula, we get:
Thus, the molality of a solution is, 0.387 mol/kg
