Chemlab

NodeJS module for chemical elements, get data regarding elements, calculate atomic weight of elements, compounds and molecules

Getting Started

Installing

npm install chemlab

And coding style

Explain what these tests test and why

var chem=require('chemlab');

console.log(chem.getElementDetails("hydrogen"));//getting detail by name
console.log(chem.getElementDetails("He")); //getting detail by symbol
console.log(chem.getElementDetails("Hefafadfg"));//error testing
console.log(chem.getAtomicWeight("NaCl",2));
console.log(chem.getAtomicWeight("CoCl2"));
console.log(chem.getAtomicWeight("FeSO4",2));
console.log(chem.getAtomicWeight("HCl"));
console.log(chem.getAtomicWeight("CH3COOH",2));
console.log(chem.getAtomicWeight("Fe2(SO4)3",2));
