Answer:
there are 4.0205 Litres of plasma in 8.5 pints
Explanation:
Recall that:
1 quart qt = 2 pints pt and 1 quart = 946 mL
∴ two pints will contain 946 mL
and one pint will be = 946 mL/2
= 473 mL
Similarly, 8.5 pints will contain 473 mL × 8.5 = 4020.5 mL
We know that :
1000 mL = 1 Litres
Hence 4020.5 mL = (4020.5 /1000)L
= 4.0205 Litres
Therefore, there are 4.0205 Litres of plasma in 8.5 pints
