20 g of sugar are dissolved in 1 L of water. Calculate the concentration of this solution.
In what units? I would write it as 20 g/L if it's a L of solution.
It's 20 grams and 1 liter, I believe.
To calculate the concentration of a solution, you need to determine the amount of solute (in this case, sugar) dissolved in a given amount of solvent (in this case, water). The concentration is commonly expressed in terms of grams per liter (g/L), which represents the number of grams of solute dissolved in one liter of solution.
In this case, you have 20 grams of sugar dissolved in 1 liter of water. Therefore, the concentration can be calculated by dividing the mass of the solute (sugar) by the volume of the solution.
Concentration = Mass of Solute / Volume of Solution
Substituting the given values:
Concentration = 20 g / 1 L
Calculating this expression, you find that the concentration of the solution is 20 g/L.
