Answer:
The molarity of the solution is 0,47 M
Explanation:
Molarity is a concentration measurement that expresses the moles of solute (in this case NaOH) in 1 liter of solution (1000ml). First we calculate the mass of 1 mol of NaOH, to calculate the moles in 58.8 g of said compound:
Weight 1 mol NaOH= Weight Na + Weight O + Weight H=23 g + 16 g +1 g
Weight 1 mol NaOH= 40 g/mol
40 g ---1 mol NaOH
58,8g---x= (58,8g x 1 mol NaOH)/40g =1,47 mol NaOH
3,1 L solution ------1,47 mol NaOH
1 L solution --------x= (1 L solution x 1,47 mol NaOH)/3,1 L solution
x= 0,47 mol NaOH ---> The molarity of the solution is 0,47 M
