Step 3: Because magnesium is the limiting reactant, the number of moles of magnesium determines the number of moles of titanium that can be formed: mol Ti = 8.23molMg = 1mol Ti 2mol Mg = 4.12mol Ti Thus only 4.12 mol of Ti can be formed. Step 4.What we have to do, is to calculate the number of chalk molecules needed to write down your name on the board. Here is how we can do that: Take one chalk and weigh it, which will be the first mass (m 1 _1 1 ) Write down your name on the board and after writing it, weigh the chalk again. That will be the second mass (m 2 _2 2 )
