Question

Enter your answer in the provided box. Calculate the composition of the following solution in mass/volume % 0.600 g NaOH per 2.00 mL % NaOH

Answer 1

30 m/v %

Step-by-step explanation:

First, we need to understand the definition of mass/volume percentage (m/v %). This is a way of expressing concentration of a substance and it means grams of a determined compound per 100 mL of solution:

m/v% = g of X substance/100 mL of solution

Having said that, if we have 0.600 g of NaOH per 2.00 mL of solution, then in 100 mL of solution we will have:

2.00 mL solution ---- 0.600 g of NaOH

100 mL solution---- x=(100 mL × 0.600 g NaOH)/ 2.00 mL = 30 g = 30 %m/v

So, the concentration of a solution containing 0.600 g of NaOH per 2.00 mL is a 30 m/v% solution.-
