Answer:
There are 5 moles of the element Clarkanium in 190 gm.
Explanation:
The atomic mass of the element Clarkanium is 38 grams.
Given mass of the element = 190 gm
The mole of a substance is the mass of the substance containing same number of atoms that is in 12-grams of carbon-12.
So the atomic mass of the element is equal to the mass of 1 mole of the element.
Therefore number of moles can be calculated by dividing given mass of the element by atomic mass of the element.
[tex]Number\ of\ Moles=\frac{Given\ mass}{Atomic\ mass}[/tex]
[tex]Number\ of\ Moles=\frac{190\ gm}{39\ gm}=5[/tex]
Since Moles is calculated in number, so it has no unit.
Hence there are 5 moles of the element Clarkanium in 190 gm.
