Question

Fill in the blanks: 87 pg = [? ]x10^[?]g

Answer 1

87 picograms are equivalent to $8.7\times 10^{-11}$ grams.

This is a unit problem, in which a derived unit must translated into a fundamental unit. A picogram is a equivalent to a trillionth of a gram, which is the fundamental SI mass unit. Mathematically speaking, we have the following equivalence:

$1\,pg = 1\times 10^{-12}\,g$

Now we proceed to find the equivalent value for this case:

$87\,pg$

$87\times 10^{-12}\,g$

$8.7\times 10^{-11}\,g$

87 picograms are equivalent to $8.7\times 10^{-11}$ grams.
