First of all we must know this:
1 mol of Ti,= 47.90 g of Ti, furthermore we can say that:
1 mol Ti = 47.90 g Ti = 6.022x10^23 formula units (atoms, molecules, ions, etc.) and in this case, we work with atoms of Ti.
Procedure:
47.90 g (1 mol) of Ti ------------------ 6.022x10^23 atoms of Ti
X ------------------ 5.74x10^22 atoms of Ti
X = 4.600 g of Ti
Answer: 4.600 g of Ti
