Question

Volume strength of 500ml solution containing 3.4gm
of H,O, is
1) 11.2 2) 6.8 3) 1.12 4.2.24
bition​

Answer 1

Answer:

HI DEAR,

Explanation:

In the above attachment we are calculating molarity for 1M in your question we have first calculate molarity

M=n/V

so we get M= 3.4×1000/34×500=0.2M

HERE n represents no of moles means weight/molecular weight .

molecular weight of H2O2 is 34g .

so for 2M we get

Volume strength =molarity × 11.2 L

0.2×11.2=2.24L

FOR H2O2 TAKE VOLUME AS 11.2 BECAUSE 2 MOLES OF H2O2 GIVES 1 MOLE OF OXYGEN .SO HERE 22.4/2 WE GET 11.2 L

HOPE IT HELPS .
