How many grams of sugar are needed to make a saturated solution of sugar in 100 g of water at 20°C?
It’s 34g.
Do you have any solubility data? I don't have all of those tables memorized.
To determine the grams of sugar needed to make a saturated solution in 100 g of water at 20°C, we need to know the solubility of sugar at that temperature. The solubility of sugar in water is approximately 2000 grams per liter (g/L) at 20°C.
First, convert the volume of water from grams to liters. Since the density of water is approximately 1 g/mL, we have:
100 g / 1 g/mL = 100 mL
Since there are 1000 mL in a liter, we have:
100 mL / 1000 mL/L = 0.1 L
Now, we can calculate the grams of sugar needed using the solubility:
Solubility of sugar = 2000 g/L
Grams of sugar needed = Solubility x Volume of water
Grams of sugar needed = 2000 g/L x 0.1 L = 200 g
Therefore, 200 grams of sugar are needed to make a saturated solution in 100 g of water at 20°C.
To determine the grams of sugar needed to make a saturated solution in 100 g of water at 20°C, we need to know the solubility of sugar in water at that temperature. Solubility refers to the maximum amount of solute that can dissolve in a given amount of solvent at a particular temperature.
The solubility of sugar in water at 20°C is approximately 2000 grams per 100 grams of water (or 20%). This means that at this temperature, 100 grams of water can dissolve up to 2000 grams of sugar to form a saturated solution.
To find the amount of sugar needed, we can use the equation:
Mass of solute = solubility x mass of solvent
Mass of solute (sugar) = 2000 g/100 g x 100 g
Mass of solute (sugar) = 2000 g
Therefore, to make a saturated solution of sugar in 100 g of water at 20°C, you would need 2000 grams of sugar.
