Question
A 5% w/v solution of NaCl contains:Group of answer choices5 g NaCl in 10 mL0.5 g NaCl in 100 mL0.5 g NaCl in 10 mL5 g NaCl in 1 L
Solution
The correct answer is 5 g NaCl in 100 mL.
Here's why:
A 5% w/v (weight/volume) solution means that there are 5 grams of solute (in this case, NaCl) in every 100 milliliters of solution. This is because the percentage is calculated as (grams of solute / milliliters of solution) * 100%. So, for a 5% w/v solution, the equation would be (5g / 100mL) * 100% = 5%.
