Answer:

4.85 grams HBr

Explanation:

To find the mass of hydrogen bromide (HBr), you need to multiply the given moles by the molar mass. The molar mass of HBr is a ratio which compares the mass (g) of HBr per every 1 mole. It is important to arrange the ratio in a way that allows for the cancellation of units (moles should be in the denominator).

Molar Mass (HBr): 1.008 g/mol + 79.904 g/mol

Molar Mass (HBr): 80.912 g/mol

0.0600 moles HBr            80.912 g
------------------------------  x  --------------------  =  4.85 grams HBr
                                             1 mole
