Answer:
4.12 mol
Explanation:
Given data:
Moles of LiOH required = ?
Volume of solution = 4.2 L
Molarity of solution = 0.98 M
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
we will calculate the moles from above given formula.
0.98 M = number of moles / 4.2 L
0.98 M × 4.2 L = number of moles
Number of moles = 0.98 M × 4.2 L
Number of moles = 4.12 mol (M = mol/L)
Explanation:
this is because of the electrolysis and the hydrogen and oxygen the experiments and all that the conditions are all right you know that song
Answer:
0.05 M
Explanation:
First we <u>convert 12 g of NaHSO₄ into moles</u>, using the <em>given molar mass</em>:
- 12 g NaHSO₄ ÷ 120.1 g/mol = 0.10 mol NaHSO₄
We can now <u>calculate the molarity of the resulting solution</u>, using the <em>calculated number of moles and the given volume</em>:
- Molarity = moles / liters
- Molarity = 0.10 mol / 2.00 L = 0.05 M
