If the human body contains about 50 deciliters of blood, and the blood has about 15 grams of hemoglobin per deciliter, and all o
Tcecarenko [31]

Answer:

The blood will contain 750 grams of O2

Explanation:

Volume of blood in the human body = 15 deciliters

Mass of hemoglobin per deciliter of blood = 15 grams

Mass of hemoglobin in 50 deciliters of blood = 50×15 = 750 grams

Since all the hemoglobin molecules are saturated with O2, mass of O2 in the blood will be the same as mass of hemoglobin molecules in the blood.

Therefore, mass of O2 in the blood is 750 grams

The forensic technician at a crime scene has just prepared a luminol stock solution by adding 19.0 g of luminol into a total vol
sasho [114]

Answer:

Molarity of Limonol is

M = 1.43mol/L

Explanation:

M = mols/L

mols = g/molar mass

Therefore, determine molar mass, divide into grams luminol and divide that by 75 mL (in liters) to obtain molarity = M.

Molar mass of Limonol = 177.16 g/mol

mols = 19g / 177.16 g/mol

mols = 0.1072mol

Molarity of Limonol, M = 0.1072 mol / 0.075

M = 1.43mol/L
