Answer:
<h3>The answer is 13.86 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 30.5 g
volume = 2.2 cm³
We have
We have the final answer as
<h3>13.86 g/cm³</h3>
Hope this helps you
<u>Answer:</u> Both the given species are isotopes of the same element.
<u>Explanation:</u>
An isotope is defined as the chemical species that have the same atomic number but a different mass number.
The atom consists of 3 subatomic particles:
- Protons: They are positively charged particles present in the nucleus of an atom.
- Electrons: They are negatively charged particles present in the orbits around the nucleus of an atom.
- Neutrons: They are neutral particles present in the nucleus of an atom.
An atomic number is defined as the number of protons or number of electrons present in a neutral atom. It remains specific for a particular element.
Mass number is defined as the sum of the number of protons and neutrons present in the nucleus of an atom.
Given values:
<u>For isotope 1:</u>
Number of protons = 11 = atomic number
Number of neutrons = 13
Mass number = 11 + 13 = 24
<u>For isotope 2:</u>
Number of protons = 11 = atomic number
Number of neutrons = 12
Mass number = 11 + 12 = 23
As the atomic number of both the isotopes is the same. Thus, they belong to the same elements.
