What is the concentration of a solution containing 25g of NaCl in a 250mL sample?"
To calculate the concentration of a solution, you need to know the amount of solute (in this case, NaCl) and the volume of the solution.
Given:
Amount of NaCl (solute) = 25g
Volume of solution = 250mL
The concentration of a solution is typically expressed in terms of grams per liter (g/L).
To calculate the concentration:
Step 1: Convert the volume from milliliters (mL) to liters (L).
250mL ÷ 1000 = 0.25L
Step 2: Use the formula for concentration:
Concentration (g/L) = Amount of solute (g) ÷ Volume of solution (L)
Concentration = 25g ÷ 0.25L
Step 3: Calculate the concentration:
Concentration = 100g/L
Therefore, the concentration of the solution containing 25g of NaCl in a 250mL sample is 100g/L.
To find the concentration of a solution, you need to know the amount of solute (in this case, NaCl) and the volume of the solution. The concentration is usually expressed in units such as grams per liter (g/L) or moles per liter (mol/L), also known as molarity (M).
Given:
Amount of NaCl = 25g
Volume of solution = 250mL = 0.25L
To calculate the concentration, you can use the formula:
Concentration = (Amount of solute) / (Volume of solution)
Substituting the given values:
Concentration = 25g / 0.25L
Now, you can divide 25g by 0.25L to calculate the concentration:
Concentration = 25g / 0.25L = 100g/L
Therefore, the concentration of the solution containing 25g of NaCl in a 250mL sample is 100g/L.
yea
If you just want the concentration in g per litre.
If there are 25 g in 250 mL
then there are 50 g in 500 mL
so there are ?? g in 1000 mL or 1 L.
