The mass of CO = 112 g
<h3>Further explanation
</h3>
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³ particles
Moles can also be determined from the amount of substance mass and its molar mass
number of atoms in 88 g CO₂ :
number of atoms in CO :
number of atoms in CO₂ = number of atoms in CO :
Mols is shorthand for molarity, a unit of measurement corresponding to moles/liter. A mole is just a number for example “ a dozen”. Mole is also spelled mol in chemistry so they do mean the same.
Thank me by clicking the heart ❤️. Thanks!
Answer:
As explained
Explanation:
My reaction will be positive and I will feel elated that a new elements has been discovered as this will be a modification of the earlier claim by berzelius and the likes that there are over 106 known elements ; Metal, Non Metals and Metalloids.
However, fitting the new discovered element in between Tin and antimony may be an issue, as the physical properties of the new elements has to be known, its melting point, metals or non metals as this is paramount to be able to classify the elements. if the elements fits in between tin and antimony, it is an indication that the elements is mot likely a metal or non-mental and may belong to group IVB or VB. Another issue is, the discoverer will have to create his own periodic table to be able to stand in with the discovery of Dimitriy Mendelev.
