Question

What is the mass of four moles of sulfur?

Answer 1

Four moles of sulfur has a mass of `"128.2 g"`.

Explanation:

From the periodic table, we can see that the molar mass of sulfur is `"32.06 g/mol"`. This means that one mole of sulfur atoms has a mass of `"32.06 g"`.

Now we need to multiply the molar mass of sulfur by 4 moles.

`4color(red)cancel(color(black)("mol S"))xx("32.06 g S")/color(red)cancel(color(black)(1"mol S"))="128.2 g S"`
