Question

1. I have a concentration of 300g of sugar for every 100 mL of water. What is the lowest possible temperature I would need to dissolve that much sugar? ____________.

Answer 1

64 °C

Step-by-step explanation:

I’m guessing that “they” are asking you to interpret a solubility curve something like the one below.

Find the point at 300 g/100 mL water on the vertical axis.

From there, draw a horizontal line until it meets the solubility curve of sugar.

Then, drop a vertical line to the temperature axis.

It appears to hit the axis at about 64 °C.

The solution is saturated at this temperature, so 64 °C is the lowest temperature at which you can dissolve 300 g of sugar in 100 mL of water.
