229.2 g of tin was heated from 46.3 to 115.7°C. How much energy was used to heat tin? (Specific heat capacity of Sn is 0.222 J/g
Dmitriy789 [7]

3531.23 J is the energy used to heat tin when 229.2 g of tin was heated from 46.3 to 115.7°C.

<h3>What is specific heat capacity?</h3>

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Q=mcΔT

Give data:

m=229.2 g

c=0.222 J/g x °C

ΔT=115.7°C - 46.3°C

ΔT= 69.4 °C

Putting value in the equation:

Q=mcΔT

Q=229.2 g x 0.222 J/g°C x 69.4 °C

Q= 3531.23 J

Hence, 3531.23 J is the energy used to heat tin.

Zn-64 = 48.63%
Ann [662]

Answer:

A = 65.46 u

Explanation:

Given that,

The composition of zinc is as follows :

Zn-64 = 48.63%

Zn-66 = 27.90%

Zn-67 = 4.10%

Zn-68 = 18.75%

Zn-70 = .62%

We need to find the  average atomic mass of the given element. It can be solved as follows :

A=\dfrac{48.63\times 64+27.90\times 66+4.1\times 67+18.75\times 68+0.62\times 70}{100}\\A=65.46\ u

So, the average atomic mass of zinc is 65.46 u.
