A. 1.00gram
B. 4.00gram
C. 8.00gram
D. 6.00gram
Correct Answer:
Option B – 4.00gram
Explanation
Avogadro’s number is an absolute number: there are 6.022×1023 elementary entities in 1 mole.
helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams.
![The number of sulphur atoms in 3.20g of SO2(g) is [O = 16.0;S = 32.0; Avogadro constant = 6.02 X 10²³] The number of sulphur atoms in 3.20g of SO2(g) is [O = 16.0;S = 32.0; Avogadro constant = 6.02 X 10²³]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png)
