Question

How many atoms is 2.34 moles of titanium?

Answer 1

2.34 moles titanium x (6.022 x 10^23)/1 mole titanium = 1.41 x 10^24

Answer 2

$1.409 \times {10}^{24} \: \: atoms$

Explanation:

Convert from moles to atoms:

2.34 mol titanium (Ti)

Determine the amount of substance, n:

n = 2.34 mol

Look up Avogadro's constant, $N_A$ , to find the number of atoms in a mole:

$N_A$ = 6.022×10^23 atoms/mol

Multiply n by $N_A$ to convert to the number of atoms, $N_{atoms}$:

Precise Answer:

$N_{atoms}$ = n× $N_A$= (2.34 mol)/1×(6.022×10^23 atoms)/(1 mol) = 1.409×10^24 atoms
