Answer:
8.2×10¯⁵ L
Explanation:
82 μL.
We can convert 82 μL to L by doing the following:
To convert from microlitre (μL) to litre(L), we need to know how many microlitre (μL) that makes up a litre (L)
Recall:
1 μL = 1×10¯⁶ L
Therefore,
82 μL = 82 μL × 1×10¯⁶ L/1 μL
82 μL = 8.2×10¯⁵ L
Therefore, 82 μL is equivalent to 8.2×10¯⁵ L
