Question

How many grams would you have if you had 1.8 moles of aluminum bromide, AlBrz? Round your answer to

two decimal places.

Answer 1

Mass = 480.04 g

Step-by-step explanation:

Given data:

Mass of AlBr₃ = ?

Number of moles = 1.8 mol

Solution:

Formula:

Number of moles = mass / molar mass

Molar mass of AlBr₃ = 266.69 g/mol

Now we will put the values in formula:

Mass = Number of moles × molar mass

Mass = 1.8 mol × 266.69 g/mol

Mass = 480.04 g
