To find the temperature in Kelvin that dissolves 400 g of sugar in 100 g of water, read the graph. If, for example, it's 60°C, convert to Kelvin: 60 + 273.15 = 333.15 K.
The provided graph illustrates the solubility of sugar in water at different temperatures. To find the temperature in Kelvin that will dissolve 400 g of sugar in 100 g of water, locate the point on the graph where the solubility is 400 g (vertical axis) in 100 g of water (horizontal axis). Then, read the corresponding temperature (°C) from the graph.
Assuming you find that temperature to be, for example, 60°C, you can convert it to Kelvin using the formula:
K=°C+273.15
So, if the temperature is 60°C:
K=60+273.15=333.15K
Therefore, the temperature in Kelvin that will dissolve 400 g of sugar in 100 g of water is approximately 333.15 K.
