The law of conservation of energy states that no energy is created nor destroyed. When using a backup generator, the generator uses energy from another resource.
From the calculations, we can see that, the change in the freezing point is -0.634°C.
<h3>What is freezing point?</h3>
The term freezing point refers to the temperature at which a liquid is changed to solid.
Given that;
ΔT = K m i
Number of moles sucrose = 35.0 g/ 342.30 g/mol = 0.1 moles
molality = 0.1 moles/ 300.0 * 10^-3 Kg
= 0.33 m
Thus;
ΔT = -1.86°C/mol * 0.33 m * 1
= -0.634°C

Answer:
Mass is Universal and weight is tied to the strength of the gravitational force of the planet .
Explanation:
The reason is because without mass you have no weight witch means if you have a certain amount of mass you will have a certain weight .
Explanation:
According to the analysis, Molarity is amount mole per volume(1L). the amount in mole would be molarity × volume in litres.
0.500M × (250/1000)L= 0.125moles.
