You prepare a solution by dissolving 319 g of glucose and 114 g of NaCl in water and bring the final volume up to 1,088 mL. What is the final concentration of glucose in g/L?
To find the final concentration of glucose in g/L, we first need to calculate the total mass of glucose and the final volume of the solution.
Given:
Mass of glucose (m₁) = 319 g
Volume of solution (V) = 1,088 mL
To get the final concentration (C), we can use the formula:
C = (m₁ / V)
However, the volume of the solution is given in milliliters (mL), while the desired concentration is in grams per liter (g/L). Therefore, we need to convert the volume from milliliters to liters by dividing by 1,000.
V (in liters) = V (in mL) ÷ 1,000
Plugging in the values, we have:
V (in liters) = 1,088 mL ÷ 1,000 = 1.088 L
Now, let's calculate the final concentration:
C = (m₁ / V)
C = 319 g / 1.088 L
Divide the mass of glucose by the volume:
C ≈ 293.60 g/L
Therefore, the final concentration of glucose in the solution is approximately 293.60 g/L.
