Answer:- 1.050 mL
Solution:- Volume is an additive property. So, we add all the three given volumes to get the total volume.
Total volume =
Since in addition, we go with least decimal places, the answer must have three decimal places as all the given numbers have three decimal places each.
Hence, the total volume should be reported as 1.050 mL.
Answer:
28.16 °C
Explanation:
Considering that:-
Heat gain by water = Heat lost by metal
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 165 g
Initial temperature = 28 °C
Specific heat of water = 4.184 J/g°C
For metal:
Mass = 4.00 g
Initial temperature = 75 °C
Specific heat of water = 0.600 J/g°C
So,
<u>Hence, the final temperature is 28.16 °C</u>
