For this problem, the solution is exhibiting some colligative properties since the solute in the solution interferes with some of the properties of the solvent. We use equation for the boiling point elevation for this problem. We do as follows:
<span>
ΔT(boiling point) = (Kb)mi
</span>ΔT(boiling point) = (0.512)(1.3/2.0)(2)
ΔT(boiling point) = 0.67 degrees Celsius
<span>
T(boiling point) = 100 + 0.67 = 100.67 degrees Celsius</span>
Answer:
The percent by mass of sodium chloride in the broth is 0.1875 %
Explanation:
Our first step is transforming the sodium chloride figure from mg to g
450mg x 1g/1000 mg= 0.45g
Now, we must calculate the percentage by using the following formula:
0.45g / 240g x 100= 0.1875%
Henceforth, we can conclude that the percentage by mass of sodium chloride in the broth is 0.1875%

Answer:
Heat, Q = 3035.073 J
Explanation:
It is given that,
Mass of water, m = 15.5 g
Initial temperature, 
Final temperature, 
The specific heat of water is, c = 4.184 J/ g°C
The heat removed or absorbed by water is given by formula as :
So, the heat of 3035.073 J is removed from 15.5 g of water.
The volume measurements won't be accurate and will be either less than or more than the anticipated figure if the graduated cylinder is accurately calibrated (depending on if the error in calibration is higher or lower). Depending on the calibration error, the calculated value may be higher or lower than the real value.
What is calibration?
Setting up an instrument so that it can generate findings for samples that fall within a tolerable range is part of the calibration process. A key component of instrumentation design is eliminating or reducing conditions that lead to faulty measurements.
Calibration attempts to reduce any measurement uncertainty by confirming the precision of test apparatus. In measuring procedures, calibration quantifies and reduces mistakes or uncertainties to a manageable level.
