Evaporating? But that’s with a boiling liquid
60
Explanation:
The number of electrons in an atom of Q-95 will be 60 electrons.
The atomic number of an atom is the number of protons in the atom of the isotope
This number is unique to every atom and their isotope
An isotope of an atom is the existence of an atom having the same atomic number but different mass numbers.
Since atomic number the same as number of protons, they are the positively charged particles in an atom.
To have a negative charge, the number of electrons must be more than that of protons.
Charge = number of protons - number electrons
charge = -1
-1 = 59 - number of electrons
Number of electrons = 60 electrons

Answer:
0.56 g
Explanation:
<em>A chemist determines by measurements that 0.020 moles of nitrogen gas participate in a chemical reaction. Calculate the mass of nitrogen gas that participates.</em>
Step 1: Given data
Moles of nitrogen gas (n): 0.020 mol
Step 2: Calculate the molar mass (M) of nitrogen gas
Molecular nitrogen is a gas formed by diatomic molecules, whose chemical formula is N₂. Its molar mass is:
M(N₂) = 2 × M(N) = 2 × 14.01 g/mol = 28.02 g/mol
Step 3: Calculate the mass (m) corresponding to 0 0.020 moles of nitrogen gas
We will use the following expression.
m = n × M
m = 0.020 mol × 28.02 g/mol
m = 0.56 g
