Answer:
Approximately 1.62894 x 10^24 atoms.
Step-by-step explanation:
To determine the number of atoms in 2.7 moles of titanium, we need to use Avogadro's number, which is the number of atoms in one mole of an element.
Avogadro's number is approximately 6.022 x 10^23. This means that one mole of any substance contains 6.022 x 10^23 particles (atoms or molecules).
The molar mass of titanium is approximately 47.87 g/mol.
To calculate the number of atoms in 2.7 moles of titanium, we can use the following formula:
number of atoms = (number of moles) x Avogadro's number
number of atoms = 2.7 moles x 6.022 x 10^23 atoms/mole
number of atoms = 1.62894 x 10^24 atoms
Therefore, 2.7 moles of titanium contains approximately 1.62894 x 10^24 atoms.
