var fDesc=new Array(); fDesc[0] = "Lab1W is a modul of the Merseburg Database MDB also separately to use.

Main Features :

1. Calculation of Concentrations for mixtures up to 6 components:

- Converting mole fractions → mass fractions
- Converting mass fractions → mole fractions (the molar masses needed are calculated from the formula automatically)
- Weighed portions (masses) of the components → Mole and mass fractions of the mixture
- Specification of mass fractions (or mole fractions resp.) and volume → Calculation of portions to be weighed („recipes“)

All results are recorded in a table which can be printed, saved or exported to MS-Excel via clipboard.

2. Conversion of Physical Units for the 32 most important quantities used in the Physical Chemistry
3. Calculator for Molar Masses with a flexible formula input"; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
