a 29.44 grams
b 58.44 grams
c 29.22 grams
d 50 grams
e 0.5 grams
5 points

Explanation:

Step1: Recall mass - mole relationship

Mass (m) = Number of moles (n)×Molar mass (M)

Step2: Substitute given values

n = 0.5 moles, M = 58.44 g/mol. So, m=0.5 mol×58.44 g/mol

Step3: Calculate the mass

m = 29.22 g

Answer:

C. 29.22 grams
