Explanation:
Carbon has 3 isotopes. Carbon-12, Carbon-13, and Carbon-14
All of them have an atomic number of 6, which means all of them have 6 protons (if they had different numbers of protons, they'd be different elements).
Since they all have 6 protons, in their elemental forms, they all have 6 electrons, too.
Carbon-12:
Atomic number: 6
Mass number: 12
protons: 6
electrons: 6
neutrons: 6
Carbon-13:
Atomic number: 6
Mass number: 13
protons: 6
electrons: 6
neutrons: 7
Carbon-14:
Atomic number: 6
Mass number: 14
protons: 6
electrons: 6
neutrons: 8
Answer: Volume = 0.01L
Explanation:
The density of a substance is given by; Density = Mass / Volume.
In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L
For the units to be uniform, we convert 1000g to Kg = 1Kg
Therefore, Volume = Mass / Density = 1Kg / 100Kg/L = 0.01L
