<u>Answer:</u> The final temperature of water is 38.5°C
<u>Explanation:</u>
To calculate the amount of heat released or absorbed, we use the equation:
where,
q = heat absorbed = 1.506 kJ = 1506 J (Conversion factor: 1 kJ = 1000 J)
m = mass of water = 30 g
c = specific heat capacity of water = 4.184 Jl/g.°C
= change in temperature =
Putting values in above equation, we get:
Hence, the final temperature of water is 38.5°C
Answer:
1.03 grams / mL
Explanation:
Mass of beaker and sample liquid = 84.64
Mass of beaker = <u>32.344</u>
Mass of the sample (subtract) = 52.296
Don't do any rounding until you are finished.
mass = 52.296 grams
volume = 50.6 mL
density = mass / volume
density = 52.296/50.6
density = 1.034 grams / mL
Rounding
The volume only has 3 dig digs
So the answer is 1.03 grams / mL
