[References] Hydrogen cyanide, HCN, is prepared from ammonia, air, and natural gas ( CH4) by the following process: Pt 2NH3 (9) + 30, (9) + 2CH,(9) 2HCN(g) + 6H,O(g) Hydrogen cyanide is used to prepare sodium cyanide, which is used in part to obtain gold from gold-containing rock. If a reaction vessel contains 5.75 g NH3, 12.0 g 02, and 5.00 g CH4, what is the maximum mass in grams of hydrogen cyanide that could be made, assuming the reaction goes to completion as written? Mass = g HCN

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
