Chemistry
1 answer:
marta [7]2 years ago
4 0

Answer:

The required mass is 22.04 g

Explanation:

We know,

Atomic mass of Co= 58g.

Now,

1 mole Co = 58 g

∴ 0.38 mole Co= (58 X 0.38) g

                         = 22.04 g

So, the required mass is 22.04 g

If 4.168 kJ of heat is added to a calorimeter containing 75.40 g of water, the temperature of the water and the calorimeter incr
Alinara [238K]

Answer:

The value of  the heat capacity of the Calorimeter  C_c = 54.4 \frac{J}{c}

Explanation:

Given data

Heat added Q = 4.168 KJ = 4168 J

Mass of water m_w = 75.40 gm

Temperature change = ΔT = 35.82 - 24.58 = 11.24 ° c

From the given condition

Q = m_w C_w ΔT + C_c ΔT

Put all the values in above equation we get

4168 = 75.70 × 4.18 × 11.24 +  C_c × 11.24

611.37 =  C_c × 11.24

C_c = 54.4 \frac{J}{c}

This is the value of  the heat capacity of the Calorimeter.
