A55 kg women 7.5 x 10 - 3 all off hemoglobin ( molar mass = 64,456 g/mol) in her blood. how many hemoglobin
molecules is this? what is this quantity in grams?

The number of molecules of hemoglobin are and the mass is 483.42 g

Explanation:

We are given:

Moles of hemoglobin =

According to mole concept:  

1 mole of compound contains number of atoms

So, moles of hemoglobin compound will contain = number of molecules.

To calculate the mass of hemoglobin, we use the equation:

Molar mass of hemoglobin = 64456 g/mol

Moles of hemoglobin =

Putting values in above equation, we get:

Hence, the number of molecules of hemoglobin are and the mass is 483.42 g

d.) circle motion requires a force to give it a centripetal acceleration.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
