Answer:

2663 g

Explanation:

We'll begin by calculating the molar mass Of X₂Y₅Z₃. This can be obtained as follow:

Molar mass of X₂Y₅Z₃ = (13.25×2) + (69.23×5) + (109.34×3)

= 26.5 + 346.15 + 328.02

= 700.67 g/mol

Finally, we shall determine the mass of 3.8 moles of X₂Y₅Z₃. This can be obtained as follow:

Molar mass of X₂Y₅Z₃ = 700.67 g/mol

Mole of X₂Y₅Z₃ = 3.8 moles

Mass of X₂Y₅Z₃ =?

Mass = mole × molar mass

Mass of X₂Y₅Z₃ = 3.8 × 700.67

Mass of X₂Y₅Z₃ = 2663 g

Therefore, the of 3.8 moles of X₂Y₅Z₃ is

2663 g
