Question

Calculate the number of moles 17gm of h2o2 (atomic weight of H=1,o=17​

Answer 1

Answer:

0.5

Explanation:

no. of moles=weight/gram molecular weight. no. of moles=17/34=0.5

Answer 2

Answer:

H=1 but o is not 17 it is 16 you write wrong okay,

so,

mole=weigh/gmm

weigh=17gm

gmm=h2o2=1*2+16*2=2+32=34

now,

mole=17/34=1/2

so mole =0.5 is right answer.
