Moles of chalk lab answer key.

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 )Answer: Determine mass of chalk stick before writing name. Determine mass of chalk stick after writing name. Calculate mass of chalk used .

All molecular and ionic compounds have unique names and formulas that are determined systematically. The mole is the standard unit for counting atomic and molecular particles. moles of Fe = 10.0 g / 55.845 g/mol = 0.17906706 mol moles of Cl 2 = 15.0 g / 70.906 g/mol = 0.211547682 mol Step 3: Moles of desired substance, FeCl 3. Since we have two given amounts, a straightforward approach to this step is to calculate the moles of 3Therefore, magnesium is the limiting reactant. 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.
