Answer 1

Answer:

6.3

Explanation:

Molar mass of oxalic acid=126g

Weight of oxalic acid present in 50 ml of 1M solution=1×50×126/1000=6.3g

Weight of oxalic acid present in 50 ml of 0.5M solution=0.5×50×126/1000=6.3/2g

So, the total amount of oxalic acid adored=6.3-6.3/2=6.3/2g

Amount of oxalic acid adored per g of charcoal=6.3×2/2=6.3
