The molarity of the solutions created by combining 0. 20 moles of hydroxide solution (NaOH) with 150 l of water is 1.33 M.
The ratio utilised to quantify the system provides saturation is called its molarity. Understanding a solution's number of moles is important since it allows you to determine the essential to tackle as well as whether the solutions is diluted or concentrated. Measures of ionic strength include molality and molarity.
Briefing :
Molarity is defined as the number of moles of solute in 1 L of solution
Number of NaOH moles present - 0.20 mol
Volume of solution - 150 mL
Since molarity is taken as number moles of solute in 1000 mL
If 150 mL contains - 0.20 mol
Then 1000 mL should contain = 0.20 / 150 x 1000 = 1.33 mol
Therefore , molarity is 1.33 M
