Question
How many atoms are in 0.30 moles of sulfur dioxide (SO2) gas at STP?
Hint: 1 mole = 6.02x10^23 particle
You should use 6.02x10^23____/1 mole____
don't forget to add specific labels so they cancel out.
Use the conversion factor above. Use the correct orientation of the conversion factor in the dimensional analysis setup. Consult to the significant figure rule for the final answer.

Significant Figure Rules
Rules
All nonzero digits are significant.
Zeros that appear between other
nonzero digits are always significant.
Zeros that appear in front of all of the
nonzero digits are called left-end zeros.
Left-end zeros are never significant.
Zeros that appear after all nonzero
digits are called right-end zeros.
Right-end zeros in a number that lacks
a decimal point are not significant.
Right-end zeros in a number with a
decimal point are significant.
This is true whether the zeros occur
before or after the decimal point.
237 has three significant figures.
1.897 has four significant figures.
39,004 has five significant figures.
5.02 has three significant figures.
0.008 has one significant figure.
0.000416 has three significant figures.
140 has two significant figures.
75,210 has four significant Ligures.
620.0 has four significant figures.
19.000 has five significant figures.
For multiplication and division problems, the answer should be
rounded to the same number of significant figures as the
measurement with the least number of significant figures.
