<u>Given data:</u>
Volume of solution measured = 0.0067 L
<u>To determine:</u>
The number of significant figures
<u>Explanation:</u>
Significant figures are the number of digits that accurately describe a measured value.
As per the rules:
All non-zero digits are significant
Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant
Hence in the given value 0.0067, there are 2 significant figures (6 &7)
C the two students watered the seeds differently
K = 0.058 yr (constant)
Fraction of the pesticide = 36 years/12 = 3 half-lives , so around 1/8 left
when 99.9 % decomposed, 0.1 % is left , so the fraction is 0.001. To reach this point, it will take around +/- 120 years
