Answer:
47.871 amu
Explanation:
Average atomic mass of an atom is obtained from the sum of the mass of the isotopes multiplicated by its natural abundance.
That means atomic mass of Ti is:
Ti = 45.953*8.00% + 46.952*7.80% + 47.947*73.40% + 48.948*5.50% + 49.945*5.30%
Average atomic mass of Ti:
<h3>47.871 amu</h3>
Answer:
The student did not have enough of the compound
Explanation:
So
As the student needs 125 g of the compound therefore the available bottle isnot enough for him.
So, the student didnot have enough of the compound
Answer:
The ratio of atoms of potassium to atoms of oxygen is 2:1
Explanation:
As the equation given is :
<h3>
</h3>
The product formed is 2 moles of potassium oxide .
Amount of potassium atom in the potassium oxide is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .
But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .
Hence , we get 4 atoms of potassium and 2 atoms of oxygen .
Ratio of potassium to oxygen atoms is - 4:2
Therefore , 2:1
