you would subtract the mass number from the protons or the atomic number because in order to find the mass number you would add the protons and neutrons :)
Answer:
Volume of the solutions
This is the most important factor for her to control.
Answer:
we can do it again and again and again and again and again and again
Answer:
volume is 7.0 liters
Explanation:
We are given;
- Molarity of the aqueous solution as 2.0 M
- Moles of the solute, K₂S as 14 moles
We are required to determine the volume of the solution;
We need to know that;
Molarity = Moles ÷ volume
Therefore;
Volume = Moles ÷ Molarity
Thus;
Volume of the solution = 14 moles ÷ 2.0 M
= 7.0 L
Hence, the volume of the molar solution is 7.0 L
