<span>Volume = 2.00 L

Molarity = 0.500 M

M = n / V

0.500 = n / 2.00

n = 0.500 * 2.00

n = 1.0 mole KNO</span>₃<span>

Molar mass KNO</span>₃ = <span>101.1032 g/mol
</span>
1 mole ------ <span>101.1032 g
</span>1.0 mole ------ ?

mass = 1.0 * 101.1032 g / 1

mass = 101.1032 g of KNO₃

hope this helps!

Aluminum has a specific heat of 0.902 j/gC. How much heat is lost when a piece of aluminum with a mass of 23.984 g cools from a
Marizza181 [45]

Answer:

Q = - 8501.99 j

Explanation:

Given data:

Specific heat of Al = 0.902 j/g.°C

Heat lost = ?

Mass of sample = 23.984 g

Initial temperature = 415°C

Final temperature = 22°C

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 22°C - 415°C

ΔT = -393°C

Q = m.c. ΔT

Q = 23.984 g× 0.902 j/g.°C × -393°C

Q = - 8501.99 j
