How many grams of sugar are needed to make a saturated solution of sugar in 100g of water at 20 degrees Celsius?
To determine the number of grams of sugar needed to make a saturated solution in 100g of water at 20 degrees Celsius, we need to find the solubility of sugar in water at that temperature.
The solubility of a substance varies with temperature, and in this case, we need to know the solubility of sugar at 20 degrees Celsius.
To find the solubility of sugar, we can refer to solubility tables or experimental data. However, I'll provide an approximate value based on typical solubility ranges.
The solubility of sugar in water at 20 degrees Celsius is around 2000 grams per liter (g/L).
To convert this solubility value to grams per gram (g/g), we divide it by 1000 since there are 1000 grams in a liter.
2000 g/L / 1000 = 2 g/g
Therefore, the approximate amount of sugar needed to make a saturated solution in 100g of water at 20 degrees Celsius is 2 grams.
