How many grams of NaOH are present in 5.0 mL of a 1.0% (m/v) NaOH solution?
Ans
5kg
To find the number of grams of NaOH present in the given solution, you'll need to use the equation:
Mass (grams) = Volume (mL) x Concentration (g/mL)
Let's break down the given information:
Volume = 5.0 mL
Concentration = 1.0% (m/v)
First, convert the concentration from a percentage to a decimal.
1.0% = 1.0 / 100 = 0.01
Next, substitute the values into the equation:
Mass (grams) = 5.0 mL x 0.01 g/mL
Multiply the volume and concentration:
Mass (grams) = 0.05 grams
Therefore, there are 0.05 grams of NaOH present in 5.0 mL of a 1.0% (m/v) NaOH solution.
