What is the mass of 4.32 mol GaI3? A. 455 g B. 1,230 g C. 1,720 g D. 1,950 g

Answer 1

Answer:

D) 1950 g

Explanation:

Given:

Moles of GaI3 = 4.32

To determine:

Mass of 4.32 moles of GaI3

Explanation:

Mass of 1 mole of GaI3 = atomic mass Ga + 3(atomic mass I)

$= 69.723 + 3(126.904) =450.435 g$

since:

mass of 1 mole of GaI3 is 450.435 g

Therefore, the corresponding mass of 4.32 moles of GaI3 would be:

$=\frac{4.32\ moles\ GaI3 * 450.435 g\ GaI3}{1\ mole\ GaI3} =1946 \ g$

Answer 2

The answer is D.1.950 g
