Final answer:
The immunoassay cell contains a volume of 8.00×10^2 nL. Converting this volume to quarts gives a result of 0.002 quarts.
Step-by-step explanation:
To find out how many quarts would be used for the assay, we need to convert the given volume of the immunoassay cell from nanoliters (nL) to quarts. First, convert 8.00×10^2 nL to liters by dividing by 10^9: 8.00×10^2 nL ÷ 10^9 = 8.00×10^-7 L. Next, convert liters to quarts by using the conversion factor: 1 L = 1.05668821 quarts. Therefore, the number of quarts used for the assay is:
8.00×10^-7 L x 1.05668821 quarts/L = 8.453504168×10^-7 quarts.
Therefore, the correct answer is (a) 0.002 quarts.
