Question
A water sample has a total dissolved solids (TDS) concentration of 500 milligrams per liter (mg/L). What is the total mass of dissolved solids (in kilograms) in 1,000 liters of the water sample?a.0.5 kgb.5 kgc.50 kg
Solution
The total dissolved solids (TDS) concentration in the water sample is 500 milligrams per liter (mg/L).
Step 1: Convert the TDS concentration to grams per liter (g/L) since 1 gram (g) is equal to 1,000 milligrams (mg). So, 500 mg/L is equal to 0.5 g/L.
Step 2: Multiply the TDS concentration (in g/L) by the volume of the water sample (in liters) to find the total mass of the dissolved solids (in grams). So, 0.5 g/L * 1,000 L = 500 g.
Step 3: Convert the total mass of the dissolved solids from grams to kilograms since 1 kilogram (kg) is equal to 1,000 grams (g). So, 500 g is equal to 0.5 kg.
Therefore, the total mass of dissolved solids in 1,000 liters of the water sample is 0.5 kg. So, the answer is a. 0.5 kg.
