SSSSS [86.1K]3 years ago
5 0

Answer:

              4.155 × 10²⁴ Atoms

Explanation:

Formula used,

Number of Atoms = Moles × 6.022 × 10²³ Atoms.mole⁻¹

Putting value of moles,

Number of Atoms = 6.90 mole × 6.022 × 10²³ Atoms.mole⁻¹

Number of Atoms = 4.155 × 10²⁴ Atoms

The atomic weight of Ga is 69.72 amu. There are only two naturally occurring isotopes of gallium:
irga5000 [103]

Answer:

71 Ga has a naturally abundance of 36%

Explanation:

Step 1: Given data

Gallium has 2 naturally occurring isotopes: this means the abundance of the 2 isotopes together is 100 %. The atomic weight of Ga is 69.72 amu. This is the average of all the isotopes.

Since the average mass of 69.72 is closer to the mass of 69 Ga, this means 69 Ga will be more present than 71 Ga

Percentage 69 Ga> Percentage 71 Ga

<u>Step 2:</u> Calculate the abundance %

⇒Percentage of 71 Ga = X %

⇒Percentage of 69 Ga = 100 % - X %

The mass balance equation will be:

100*69.72 = x * 71 + (100 - x)*69

6972 = 71x + 6900 -69x

72 = 2x

x = 36 %

71 Ga has a naturally abundance of 36%

69 Ga has a naturally abundance of 64%
