Molarity is defined as the number of moles of solute in 1 L of solution
molarity of given HCl solution is 2.00 M
this means that there are 2.00 mol of HCl solute in 1 L solution
so if 1000 mL contains - 2.00 mol
then 25.0 mL contains - 2.00 mol / 1000 mL/L x 25.0 mL = 0.0500 mol
number of moles of solute are 0.0500 mol
molarity of given HCl solution is 2.00 M
this means that there are 2.00 mol of HCl solute in 1 L solution
so if 1000 mL contains - 2.00 mol
then 25.0 mL contains - 2.00 mol / 1000 mL/L x 25.0 mL = 0.0500 mol
number of moles of solute are 0.0500 mol
The number of moles of solute that are present in 25.0 mL of 2.00 M HCl is equal to 0.05 moles.
How do we calculate moles from molarity?
Molarity (M) of any solution is define as the number of moles (n) of solute present in per liter of the solution (V) and represented as:
M = n/V
Given that, Volume of solution = 25mL = 0.025L
Molarity of HCl = 2M
Moles = (2)(0.025) = 0.05 moles
Hence required moles of solute are 0.05 moles.
