number of moles = mass / molar massTherefore, n=20.82g/6.34gmol-1=3moles
Using a copy of the periodic table, look up the Mass and Atomic numbers of Silicon. Mass number = 28; Atomic number = 14. The Atomic number is equivalent to the number of Protons in an atom, so there are ...
To make crystals of copper chloride from copper carbonate andd dilute HCl, you will firstly need to add an excess of copper carbonate to the dilute HCl (keep adding until no more reacts). Next, take the s...
We need to use the equation : Moles=Mass/MrSubstitute in value : moles= 36/12Therefore number of moles in 36 grams of carbon is 3.
