If 0.30 mol NaCl goes into a solution with 4.00L water, the molarity of NaCl is
0.30 mol / 4.00L = 0.075 mol/L ..
0.30/4.00=0.075mol/l
To determine the molarity (M) of NaCl in the solution, you can use the formula:
Molarity (M) = Number of moles of solute / Volume of solution (in liters)
Given:
Number of moles of NaCl = 0.30 mol
Volume of solution = 4.00 L
Substituting the values into the formula, we get:
Molarity (M) = 0.30 mol / 4.00 L
Calculating this, we find:
Molarity (M) = 0.075 M
Therefore, the molarity of NaCl in the solution is 0.075 M.
To find the molarity of a solution, you need to divide the number of moles of solute by the volume of the solution in liters.
Given that the number of moles of NaCl is 0.30 mol and the volume of the solution is 4.00 L, we can use the formula:
Molarity (M) = Number of moles of solute / Volume of solution (in L)
Plugging in the values, we get:
Molarity (M) = 0.30 mol / 4.00 L
Calculating this, we find:
Molarity (M) = 0.075 M
Therefore, the molarity of NaCl in the solution is 0.075 M.
