Hydrogen mass is 1, the atom with mass number 7 is Lithium
I believe it forms an anion that has a larger radius.
total pressure = ( 705 torr + 231.525torr) = 936.525torr
Answer:
Molarity = 3 M
Explanation:
Given data:
Volume of solution = 2 L
Number of moles of HCl = 6 mol
Molarity = ?
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
by putting values,
Molarity = 6 mol / 2 L
Molarity = 3 M (M = mol/L)
