Question

HOW MANY ML OF S02 GAS ARE PRESENT AT STP IN A 100g SAMPLE THAT IS 6.4% SO2 BY MASS ?????

SOLVE THIS GUYS .........☺☺☺

Answer 1

We Know... That

Wt. in gram/Molecular Weight = Mole

So, 100/64 [ mol. wt. of SO2 is 64}

And it is asked for STP

So, 100*22.4/64

2240/64

= 35

So now the SO2 is 6.4 percent in the sample

Therefore 6.4 * 35/100

= 224/100

= 2.24 mL
