Question: If 10 grams of NaCl is dissolved in 500 mL of water, what is the concentration in g/L? (2020)

Options:

Correct Answer: 20 g/L

Solution:

Concentration = (10 g / 0.5 L) = 20 g/L.

If 10 grams of NaCl is dissolved in 500 mL of water, what is the concentration in g/L? (2020)

If 10 grams of NaCl is dissolved in 500 mL of water, what is the concentration in g/L? (2020)

Step 1: Understand that concentration is the amount of solute (NaCl) divided by the volume of solvent (water).
Step 2: Identify the amount of NaCl, which is 10 grams.
Step 3: Convert the volume of water from milliliters to liters. Since 500 mL is equal to 0.5 L, we will use 0.5 L.
Step 4: Use the formula for concentration: Concentration = (amount of solute in grams) / (volume of solution in liters).
Step 5: Plug in the values: Concentration = (10 g) / (0.5 L).
Step 6: Calculate the concentration: 10 g divided by 0.5 L equals 20 g/L.
