1. 2. CNG is an important transportation fuel. When 100g CNG is mixed with 208g oxygen in vechicles, it leads to the formation of CO2 and H2O and produces large quantity of heat during this combustion, then the amount of carbon dioxide produced in germs is (nearest integer) [Assume CNG to be methane] In a solid AB, A atoms are in ccp arrangement and B atoms occupy all octahedral sites. If two atoms from the opposite face are removed, then the resultant stoichiometry of the compound is AxBy. The value of x is. (nearest integer)
