Answer:
375 g
Explanation:
Let the total mass of the solution = x g
Given that the mass of NaOH in the solution = 15.0 g
Thus, mass of the solvent = x - 15.0 g
Given that the mass % of the solution = 4 %
So,
So,
<u>Mass of the solution = 375 g</u>
What is the mass of 25.0 grams of HF

The empirical formula is obtained by calculating the mole ratios of the atoms in the elements.
The number of moles =mass/ R.A.M
For hydrogen, no. of moles=8/1=8
For oxygen, no. Of moles=64/16=4
The tabular solution is attached.
