The number of moles of 1.36X10²² atoms of Cu is 2.140 x 10²°.
The SI unit of measurement known as the mole is used to determine the amount of any substance. Mol is the symbol for it.
Cu is the symbol of an element called copper. It is necessary for the body in micro amounts.
Given that the moles of 1.36 x 10²² atoms of Cu
n = m/M
n = moles = ?
m = mass(g) = 1.36 x 10²² atoms of Cu
The molar mass of Cu is 63.546 u
Putting the value in the formula:
n = 1.36 x 10²² / 63.546 = 2.140 x 10²°
Thus, the number of (mol) for 1.36X10²² atoms of Cu is 2.140 x 10²°
