Question

3x10-21 moles of an amino acid having molecular mass 200g mol', would have molecules;
a. 200
d. 36000
b. 1800 c. 300

Answer 1

Answer:

answer will be 1800 or more accurate 1806

Explanation:

multiply the number of moles by avogadro's number will gives us the number of molecules

Answer 2

Answer:

1800

Explanation:

As we know accordingly to Avogadro's Law

1 mole = 6.02 * 10+²³ particles

So

3 * 10-21 moles = (6.02 * 10+²³) ( 3 * 10-²¹ )

= 1806 ~ 1800
