When you examine fluid that you have drawn from a blood vessel in someone's arm, you find that it is relatively high in carbon d
ziro4ka [17]

Answer:

The given blank can be filled with a venule.

Explanation:

A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.  

The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.

How many grams of CaCl2 are in 0.75M solution with a volume of 1L
grandymaker [24]

83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.

Explanation:

Molarity or molar concentration is the number of moles of solute that can be dissolved in 1 L of a solution.

let us find the number of moles

n=C*V                Concentration is 0.75M

                          Volume is 1000ml.

n= 0.75*1

n= 0.75

This means there are 0.75 moles of CaCl2 in 1000 ml of solution of .75M.

Molar mass of CaCl2 is = 40.08+ 2(35.5)

                                       =   110.98 gms

Thus 1 MOLE OF CaCl2 weighs 110.98

         so 0.75 moles will weigh  110.98*0.75

                                              =  83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
