The magma from a volcano is cooled
<u>Answer:</u>
• 7.64 g Bi = 2.20 x 10²² atoms
• 35.8 g P = 6.95 x 10²³ atoms
<u>Explanation:</u>
First calculate the number of moles in each sample:
no. of moles = mass ÷ molar mass (RMM)
• 7.64 g Bi = 7.64 ÷ 209
= 0.03656 mol
• 35.8 g P = 35.8 ÷ 31
= 1.155 mol
Then multiply the number of moles by Avogadro's constant (6.02x10²³):
• 0.03656 x 6.02x10²³ = 2.20 x 10²² atoms
• 1.155 x 6.02x10²³ = 6.95 x 10²³ atoms
