How many atoms are in 0.075 mol of titanium?
A
1.2 X 10-25
B
2.2 X 1024
C
6.4 x 102
D
4.5 x 1022
Explanation: 

Detailed explanation-1: -How many atoms are in . 075 mol of titanium? Because There are 6.022x10^23 atoms per mole; therefore, (6.022x10^23*(0.075)=04.5x10^22 atoms of titanium.

Detailed explanation-2: -Since we know that there are 6.022⋅1023 atoms in every mole of a substance (Avogadro’s Number), there are 6.022E23⋅0.750 atoms of Zn in 0.750 mols of Zn.

Detailed explanation-3: -Answer and Explanation: There are 2.26 x 1023 atoms of titanium present in this sample.
