Question

how many microliters are in 6500 nanoliters? *
6.5
65000
0.65
0.065
how many meters are in 4 millimeters? *
0.4

Explanation:

Step1: Recall unit - conversion factor

1 nanoliter ($nL$) = 0.001 microliter ($\mu L$).

Step2: Set up conversion equation

Let $x$ be the number of microliters in 6500 nanoliters. Then $x = 6500\times0.001$.

Step3: Calculate the result

$x=6.5$.

Answer:

A. 6.5
