Question

14. Calculate the mass of the following
(a) 0.2 mole of Sulfur atom
(b) 0.5 mole of oxygen atom
​

Answer 1

Answer:

Mass of sulfur- 6.4g

Mass of oxygen- 8g

Explanation:

We can calculate the mass of each element using the mole formula.

$Moles = \frac{Mass}{Molar Mass}$

For a sulfur atom, we have-

The mole of sulfur- 0.2 mol

The molar mass of a sulfur atom- 32g/mol

$0.2 = \frac{Mass}{32} \\0.2 * 32 = Mass \\6.4 g= Mass$

The mass of sulfur is 6.4g.

For an oxygen atom, we have-

The mole of oxygen- 0.5 mol

The molar mass of an oxygen atom- 16g/mol

$0.5 = \frac{Mass}{16} \\0.5 * 16 = Mass \\8 g= Mass$

The mass of oxygen is 8g.
