Hey there!:
Molar mass FeF3 = 112.84 g/mol
Number of moles = mass of solute / molar mass
Number of moles = 24.0 / 112.84
Number of moles = 0.212 moles of FeF3
Hope that helps!
First of all, the formula for finding Kelvin is Celsius + 273
Therefore, if we subtract 273, we get the temperature in degrees
120 - 273 = - 153
Therefore, the answer is (1), or -153 degrees Celsius
Hope this helped!! :D

Answer:
im pretty sure its b. sand and iron
ik that magnetism easily separates iron
The scale will read <u>112 grams.</u>
Why?
Since we already know the percent error of the scale (12%) and we also know the mass of the block that is placed on the scale, we can calculate what will be the read of the scale by using the following formula:

We can see that the scale will read 112 grams.
Let's verify that we are right by using the following formula to verify if the obtained value for the scale read will be 12%:

Hence, we can see that the scale will read <u>112 grams.</u>
Have a nice day!
