Answer:
Mass = 627.2 g
Explanation:
Given data:
Number of moles of barium nitrate = 2.4 mol
Mass of barium nitrate = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of barium nitrate = 261.337 g/mol
Mass = 2.4 mol × 261.337 g/mol
Mass = 627.2 g
The formula for an isotope of oxygen with nine neutrons, including the mass number and the atomic number is 17/8 O.
<h3>What is an isotope?</h3>
Isotope is any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
This means that atoms of isotopes will have the same atomic number but a different mass number.
According to this question, an isotope of oxygen has 9 neutrons. If oxygen has an atomic number of 8, the formula of this particular isotope is as follows: 17/8 O.
