Answer:
208.7°C was the initial temperature of the limestone.
Explanation:
Heat lost by limestone will be equal to heat gained by the water
Mass of limestone =
Specific heat capacity of limestone =
Initial temperature of the limestone =
Final temperature = =T = 51.9°C
Mass of water=
Specific heat capacity of water=
Initial temperature of the water =
Final temperature of water = =T = 51.9°C
On substituting all values:
208.7°C was the initial temperature of the limestone.
Answer:
Concentration solution A was 0.5225 M
Explanation:
10.00 mL of solution A was diluted to 50.00 mL and yields 50.00 mL of solution B
According to laws of dilution-
where, and
are concentration of solution A and B respectively
and
are volumes of solution A and B respectively
Here = 0.1045 M,
= 50.00 mL and
= 10.00 mL
Hence,
So, concentration solution A was 0.5225 M
