Answer:

[tex] \huge{ \boxed{98.5 \:g }}[/tex]

Explanation:

The mass can be found by using the formula:

m = M × n

where:

m is the mass in grams

M is the molar mass in g/mol

n is the number of moles

From the question:

M = 197 g/mol

n = 0.5 moles

[tex] \therefore \: m = 197 \times 0.5 \\ = 98.5 \: g[/tex]
