To find the mass of BaCl2, we first need to determine the molar mass of BaCl2.

The molar mass of BaCl2 can be calculated as follows
Ba: 137.33 g/mo
Cl: 35.45 g/mol

Molar mass of BaCl2 = 137.33 g/mol + 2(35.45 g/mol
Molar mass of BaCl2 = 137.33 g/mol + 70.9 g/mo
Molar mass of BaCl2 = 208.23 g/mol

Now, we can use the formula
m = n * M

where
m = mass of BaCl
n = number of moles of BaCl2 = 0.45 mole
M = molar mass of BaCl2 = 208.23 g/mol

m = 0.45 moles * 208.23 g/mo
m = 93.7 g

Therefore, the mass of BaCl2 is 93.7 grams.
