Question

find the weight of 0.5 mole of O2​

Answer 1

moles=mass/molar mass

so moles=0.5

molar mass=32

mass=moles*molarmass

=0.5 *32=16gms

Answer 2

Answer:

16 grams

Explanation:

As we know that;

No. of moles = weight /molecular mass

so here;

given , moles = 0.5 and

molecular mass =16 x 2= 32

then weight = moles x molecular mass

= 32x0.5= 16 grams
