Question

1-    8 quarts = 1 peck, and 4 pecks = 1 bushel. How many quarts are there in half a megabushel?

2- Find the number of moles in 32.0 of each of the following elements. Which of these elements contains the greatest number of atoms? a)C b) O

Answer 1

1

1 megabushel = 1032056.74 bushel then half megabushel = 1032056.74/2 = 516028.37 bushel

1 bushel = 4 pecks then 516028.37 bushel = 516028.37 X 4 = 2064113.48 pecks

1 peck = 8 quarts then 2064113.48 pecks = 2064113.48 X 8 = 16512907.8 quarts

half a quarts = 16512907.8 quarts

2

a) C molar mass of C= 12 gm/mole then 32 gm of C = 32/12 = 2.667 mole

32 gm C = 2.667 mole

b) molar mass of O = 16 g/mol then 32 gm of O = 32/16 = 2 mole

Carbon contain greatest number of atom because carbon is 2.667 mole and oxygen is only 2 mole.
