HELP PLEASE LOOK AT PIC

I believe 2 and 3 because if the water is evaporating then it leaves more space for the salt, and 2 because of the water when it turns to ice then the ice is taking the water and salt and turning them both together into ice. I am not completely sure but this my assumption.

step-by-step explanation:

do you have a copy of the table?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
