Question 2

Calculate the mass, in grams, of a single molecule of sulfur hexafluoride ( $SF6\text{SF}_6$ ), using the data below.

Relative atomic masses ( $A_r$ ): $S=32.1\text{S} = 32.1$ , $F=19.0\text{F} = 19.0$
Avogadro constant = 6.02 × 10²³ per mole

Give your answer in standard form to 3 significant figures.
