Read each question carefully and show all your work. Use the periodic table to find the molar mass of each element. Round all molar masses to two decimal places.
1. The is the mass in grams of one mole of a substance.
2. Avogadro's number is particles per mole.
3. To convert from moles to grams, you must by the molar mass.
4. To convert from grams to moles, you must by the molar mass.
Calculate the molar mass for the following compounds:
5. H₂O
6. CO₂
7. NaCl
Perform the following conversions. Show all your work.
8. How many grams are in 3.5 moles of H₂O?
9. How many moles are in 72.0 grams of CO₂?
10. What is the mass of 0.75 moles of NaCl?
11. The molar mass of an element is numerically equal to its atomic mass in grams.
