how many significant figures are there in the measured quantity 0.670 mg?
Answer
Explanation:
Step1: Recall significant - figure rules
Non - zero digits are always significant. Zeros between non - zero digits are significant. Trailing zeros in a number with a decimal point are significant.
Step2: Analyze 0.670
The non - zero digits 6 and 7 are significant. The zero after 7 is a trailing zero in a number with a decimal point, so it is also significant. So, there are 3 significant figures.
Answer:
D. Three significant figures
