metal rusting in salt water
Mechanical! Hope I helped
We are given with an element Iron, Fe, with a mass of 235.45 g. We are tasked to solve for its corresponding molar mass in mol. We need to find first the molecular weight of Iron, that is
Fe= 55.845 g/mol
With 235.45 g sample, its corresponding mol is
mol Fe= 235.45 g x 1 mol/55.845 = 4.22 mol Fe
Therefore, molar mass of Iron is 4.22 mol
The buret should be conditioned before loading it with the titrant.
<h3>What is a Buret?</h3>
This is defined as laboratory apparatus which is used in quantitative chemical analysis to measure the volume of a liquid or a gas.
It should be conditioned with the titrant solution to prevent dilution from occurring as a result of cleaning it with water.
