Question

The volume of gas at NTP produced by 100g
of CaC, with water:
CaC, + 2H,0 + Ca(OH)20 + C,H, )
(1) 70 litre
(2) 35 litre
208)
(3) 17.5 litre
(4) 22.4 litre​

Answer 1

Answer:

It's option (2) 35 litres.

Explanation:

*Molecular mass of CaC2 = 64      

* NTP = 22.4

* Gram / molelular mass = volume of gas in litres / NTP

    100 / 64 =volume of gas in litres / 22.4

100 / 64 x 22.4 = volume of gas in litres

* volume of gas in litres = 35
