Answer:
64,433.6 Joules
Explanation:
<u>We are given</u>;
- Volume of water as 220 mL
- Initial temperature as 30°C
- Final temperature as 100°C
- Specific heat capacity of water as 4.184 J/g°C
We are required to calculate the amount of heat required to raise the temperature.
- We know that amount of heat is calculated by;
Q = mcΔT , where m is the mass, c is the specific heat, ΔT is the change in temperature.
Density of water is 1 g/mL
Thus, mass of water is 220 g
ΔT = 100°C - 30°C
= 70°C
Therefore;
Amount of heat, Q = 220g × 4.184 J/g°C × 70°C
= 64,433.6 Joules
Thus, the amount of heat required to raise the temperature of water is 64,433.6 Joules

Answer:
108.76 amu is the mass of 109Ag
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
Since the element has only 2 isotopes, so the let the percentage of first be x and the second is 100 -x.
For first isotope, 109Ag:
% = 51.82 %
Mass = x amu
For second isotope, 107Ag:
% = 100 - x
= 100 - 51.82 % = 48.18 %
Mass = 106.905 amu
Given, Average Mass = 107.868 amu
Thus,
Solving for x, we get that:
x = 108.76 amu
<u>108.76 amu is the mass of 109Ag</u>
