The mass of the silver : 4.6 g
<h3>Further explanation </h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
∆T = temperature difference :
The specific heat of silver is 0.235 J/gºC
Q = heat = 26 J
The mass :
Answer: I just took the test, the answer is A.
Explanation:
Mass number is the sum of protons and neutrons.
Atomic number is the total number of protons present.
Mass number = protons + neutrons
Atomic number = protons present.
From the above equations we can conclude that,
Atomic number= Mass number- neutrons.
Thus we can find out the atomic number by subtracting the number of neutrons from the mass number.
It’s definitely persuade!
