Question

What weight in grams is represented by 1.5 moles of sulphur dioxide?

Answer 1

Moles = mass/molar mass

That means mass= moles x molar mass

Molar mass of SO2 = 62
moles is given as 1.5

Therefore mass = 62 x 1.5
                          =  93 g

Answer 2

Answer : The weight of sulfur dioxide in grams is, 96 grams.

Solution : Given,

Moles of sulfur dioxide, $SO_2$ = 1.5 moles

Molar mass of sulfur dioxide, $SO_2$ = 64 g/mole

Formula used :

$\text{Mass of }SO_2=\text{Moles of }SO_2\times \text{Molar mass of }SO_2$

$\text{Mass of }SO_2=(1.5mole)\times (64g/mole)=96g$

Therefore, the weight of sulfur dioxide in grams is, 96 grams.
