Molar mass NaOH = 40.0g/mol
0.5mol = 20.0g NaOH
Solution is 0.5M
Therefore 1000mL will contain 20.0g NaOH
Volume that contains 0.20g NaOH = 0.2/20.0*1000 = 10.0mL
Volume required = 10.0mL .
0.5mol = 20.0g NaOH
Solution is 0.5M
Therefore 1000mL will contain 20.0g NaOH
Volume that contains 0.20g NaOH = 0.2/20.0*1000 = 10.0mL
Volume required = 10.0mL .
