identify the number of significant figures in each measurement. type the correct answer in each box. use numerals instead of words. 0.052301 km: significant figures 400 cm: significant figures 50.0 m: significant figures 4,500.01 mi: significant figures
Answer
Explanation:
Step1: For 0.052301 km
Non - zero digits and zeros between non - zero digits are significant. Leading zeros are not significant. So there are 5 significant figures.
Step2: For 400 cm
Trailing zeros without a decimal point may or may not be significant. Here, assuming no additional information, it has 1 significant figure.
Step3: For 50.0 m
Trailing zeros after a decimal point are significant. So it has 3 significant figures.
Step4: For 4,500.01 mi
Non - zero digits and zeros between non - zero digits and trailing zeros after a decimal point are significant. So it has 6 significant figures.
Answer:
5 1 3 6
