astronauts on the International Space Station are staying​ healthy, so they have them routinely test their blood. One type of​cholesterol, High Density Lipoprotein or​ HDL, has a molecular mass of 387 grams per mole​ [g/mol]. The normal range is between 40 and 60 milligrams per deciliter​[mg/dL]. In a sample of 0.081 liters​ [L], how many moles​ [mol] of hemoglobin must be present for the doctors to say an astronaut has high HDL​ cholesterol? Place your answer in scientific notation with the form Z.ZZ×10X.

Question
