Question
Determine the number of significant figures in the following measurements 345 cm, 6.050 m, 1.310 x 10²² atoms, 0.00134 m
Correct Answer
Option C is the correct answer.
Detailed Explanation
345 cm has 3 significant figures (all non-zero digits). 6.050 m has 4 significant figures (trailing zero after decimal is significant). 1.310 x 10²² has 4 significant figures (the coefficient 1.310 has four digits). 0.00134 m has 3 significant figures (leading zeros are not significant). Therefore, the counts are 3, 4, 4, and 3.
Hint
Apply the rules for significant figures: leading zeros not significant, trailing zeros after decimal are significant.
