Molar Masses
This is the molar mass of CN
26 g/mol
This is the atomic weight of Neon? (Ne)
20 g/mol
This is how many moles are in 80 g of NH3
4.71 moles
10 grams of Zinc (Zn) has more or less particles than 10 grams of Sodium (Na).
Fewer, because they weigh more, so it takes less to get to 10 grams. (Elephants and Eggs)
This is the molar mass of NaCl
58.5 g/mol
This is the name and symbol of the element with an atomic weight of about 63.5 g/mol.
Copper (Cu)
This is how much 6.2 moles of CO2 weighs.
272.8 g
This would be the heavier sample between 1 mole of Silver and 1 mole of Gold.
1 mole of Gold
How often do I want to hear chemistry jokes?
Periodically
This is the molar mass of fluorine gas
38 g/mol because fluorine gas is F2 not F
These are the 7 naturally occurring diatomic elements.
What is Iodine, Hydrogen, Nitrogen, Fluorine, Oxygen, Chlorine, Bromine
On our proportion, this is the name of the number that goes in the bottom left spot.
Molar Mass of Compound
Daily Double! Rice represented this in our counting by weight lab. Explanation also required.
Hydrogen, because it was our smallest particle. Because it is our smallest particle, we use it to measure all the others.
What should you do if a chemist dies?
Barium
This is the molar mass of vinegar. Formula: CH3COOH
60 g/mol
This element, which used to be called Phlogiston, now has a new name.
Hydrogen
You have 2.32 moles of nitrogen gas. It weighs this much.
65 grams.
This would be the sample with more particles between 1 mole of Silver and 1 mole of Gold.
Neither, both contain 1 mole, so both have the same number of particles.
Why was one element not speaking to the other?
This is the molar mass for (NH4)3PO4
149 g/mol
Each element has a specific weight. They are all relative to this thing.
The weight of Hydrogen being 1.
If you drank 1 liter of water, you would have consumed this many moles of water.
55.5 moles
In our food lab, Corn had a weight of .18 g and represented Beryllium, because it had a relative mass of 9. A cranberry weighs .80 grams and based on its RELATIVE WEIGHT it would represent this element: _____
Calcium, atomic weight is 40 g/mol, 40x that of Rice/Hydrogen
