Answer:
0.000153DaL
Explanation:
We have been given:
15.3mL to convert to DaL
DaL is a unit of volume which indicates a decaliter.
This implies that;
1 Da L = 1 x 10²L
So:
1 mL = 1 x 10⁻³L
So 15.3mL will give 15.3 x 10⁻³L
So;
1 x 10²L = 1 DaL
15.3 x 10⁻³L will give = 15.3 x 10⁻⁵DaL
Therefore, this is 0.000153DaL
Answer : The specific heat of unknown sample is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of unknown sample = ?
= specific heat of water =
= specific heat of copper =
= mass of unknown sample = 72.0 g = 0.072 kg
= mass of water = 203 g = 0.203 kg
= mass of copper = 187 g = 0.187 kg
= final temperature of calorimeter =
= initial temperature of unknown sample =
= initial temperature of water and copper =
Now put all the given values in the above formula, we get
Therefore, the specific heat of unknown sample is,
