(MW H2O: 18 g/mol, MW C3H8O3: 92 g/mol).
What is 2 M (molar)?
100
The charge of an anion
What is negative?
100
The moles of carbon dioxide, CO2, formed by the decomposition of 5 moles of aluminum carbonate, Al2(CO3)3.
Al2(CO3)3 → Al2O3 + 3 CO2
What is 14 moles
200
The molecular weight of glucose (C6H12O6).
What is 180 g/mol
200
Formula to find density
What is mass/volume?
200
The mole fraction of 184g of glycerol when mixed with 180 g of water.
(MW H2O: 18 g/mol, MW C3H8O3: 92 g/mol).
What is .17
200
The charge of a cation
What is positive?
200
Moles of carbon dioxide, CO2, that can be formed by the decomposition of 5 moles of aluminum carbonate, Al2(CO3)3.
Al2(CO3)3 → Al2O3 + 3 CO2
What is 15 moles?
300
The molecular weight of oxygen gas.

6.022 x 10^23
What is Avogadro's Number
300
The solvent when you are dissolving rocks in milk.
What is milk?
300
4NH3(g) + 6NO(g)→5N2(g) + 6H2O(g)
Moles of each reactant if 13.7 moles of N2(g) is produced
What is:
10.96 moles NH3(g) and 16.44 moles NO(g).
400
The molecular weight of .4 moles of H2S
What is 13.62 g
(Since we want the weight of 0.4 moles of H2S, we simply multiply the weight of 1 mol of H2S (32.06) by 0.4. The answer comes out to 13.62 g.)
400
The number of atoms in one mole of substance
What is 6.022x10^23 atoms?
400
The solute when you accidentally dissolve toxic waste into your well-water.
What is toxic waste?
400
Balanced from of
KClO3 (s) --> KCl (s) + O2 (g)
What is
2 KClO3 (s) --> 2 KCl (s) + 3 O2 (g)
500
The molecular weight of .2 moles of KI
What is 33.2 g
(Since we want the weight of 0.2 moles of KI, we simply multiply the weight of 1 mol of KI (166) by 0.2. The answer comes out to 33.2 g.)
500
The number of protons in Potassium
What is 19?
500
