  • Question 2
    60 seconds
    Q. What is Avogadro's Number? 
    answer choices
    6.02 x 1023
    - 6.02 1023
    6.02 x 1022
    6,020,000,000,000
  • Question 3
    60 seconds
    Q. What is the molar mass of H2O?
    answer choices
    6.02 x 1023
    16 grams
    18 grams
    15.99999 grams

    Q. How many moles are in 32 grams of Oxygen (O)? 
    answer choices
    3
    2
    1
    4
  • Question 7
    60 seconds
    Q. How many moles are in 20 grams of Ca (Calcium)?
    answer choices
    0.5 
    1
    3
    20
  • Question 8
    120 seconds
    Q. How are the mole and atomic masses of elements related?  
    answer choices
    The atomic mass of any substance is always equal to 1 mole of that substance 
    The atomic mass added up with itself by 6.02 x 1023 equals the amount of atoms
    The atomic mass is the amount of protons plus number of atoms
    Atoms combined make up molecules, which are the measurement of atomic masses 
  • Question 9
    60 seconds
    Q.

    What is the molar mass when you have 4 moles of CO2?

    answer choices

    176 grams

    54 grams

    128 grams

    280 grams

  • Question 10
    120 seconds
    Q. What do two or more Avogadro's make? 
    answer choices
    Guaca-MOLE
    Chemistry = fun
    Hagerman more crazy
    You snapchatting your life away 
  • Question 11
    120 seconds
    Q.

    What is the difference between the atomic mass of an element and the molar mass of a compound?

    answer choices

    The atomic mass is the added sum of ALL of the elements

    The molar mass can be either the added sum of ALL the masses or the mass of a particular element

    The molar mass and the atomic mass are always the same

    The atomic mass of a compound is the average of H2O

  • Question 12
    120 seconds
    Q.

    Why is the mole used to measure the atom?

    answer choices

    Atoms are extremely tiny particles, and their size varies from element to element

    Atoms are all the same size for every element

    Some atoms cannot be counted using the mole
