getMolarMass: getMolarMass

In sergmonic/AtomicWeights: Atomic Weights & Molar Mass

Description

This function return the standard molar mass and its standard uncertainty for a given molecular formula. The standard atomic weights used are obtained from getAtomicWeight()

Usage

getMolarMass(atomsType, atomsNumber = 1)

Arguments

atomsType	A string vector with chemical symbols for the elements in the molecular formula
atomsNumber	A int vector with the number of atoms for each element in the molecular formula (by default =1)

Details

The function uses the GUM aproach based on the molecular formula(1).

Value

A data.frame with the molar mass (MM) and its standard uncertainty (u_MM)
