Question

A sample of sulfuryl fluoride, SO2F2, has a mass of 19.2 g. What amount, in moles, does this mass represent?

Answer 1

0.188 moles.

Step-by-step explanation:

Molar mass of SO2F2

= 32 + 2*16 + 2 * 19

= 102 g.

So 19.2g = 19.2 / 102

= 0.188 moles.

Answer 2

0.188 moles

Step-by-step explanation:

moles=mass/molar mass

moles= 19.2/ (32+32+38)

moles= 0.188
