Explanation:
Hello,
In this case, we can compute the the freezing point depression by using the following formula:
Whereas the freezing point of pure water is 0 °C van't Hoff factor for glucose is 1, the molality is computed as shown below and the freezing point constant of water is 1.86 °C/m:
Thus, the freezing point of the solution is:
Regards.
Answer:When making observations during an experiment, Descriptions of any changes in the system following an action and Descriptions of any non-changes in the system following an action a list of possible errors must be included. The correct option is C and D.
Explanation: During a scientific experiment procedures, observation is usually carried out to take into consideration an active information from the natural source. Data can be collected by the observer:

Answer:
317.7778 g
Explanation:
Given data:
Flour required for 18 cup cakes = 260 g
Flour required for 22 cup cakes = ?
Solution:
We will calculate the flour required for 1 cup cake.
260 g /18 = 14.4444 g
Fluor required for 22 cupcakes,
22× 14.4444 g = 317.7778 g
In short,
22 cupcake/18 cup cake×260 g = 317.7778 g
