The density of the patient's hemoglobin in their blood in units of g/ml = 0.2g/mL
<h3>Calculation of hemoglobin density</h3>
Hemoglobin is the red blood cell pigment that transports oxygen to the body cells.
1 gram of hemoglobin = 2.15mg
Blood volume of the patient is = 4.9ml
Density= mass/volume
Therefore the density of patients hemoglobin= 1/4.9 = 0.2g/mL

In Chemistry class, tongs are used to pick up or hold hot objects.
Answer:
The molarity of the solution is 0,12 M.
Explanation:
We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KOH) in 1000ml of solution (1 liter):
0,25 L solution----- 0,030 moles of KOH
1 L solution----x= (1 L solution x 0,030 moles of KOH)/0,25 L solution
x= 0,12 moles of KOH ---> <em>The solution is 0,12 M</em>
Viscosity is the resistance for liquids to flow. So the lower the viscosity, means the liquid does not have as much resistance to run or flow. So I believe it's water.
Oxygen is fairly smaller than beryllium. The two have the same amount of orbital shells, but oxygen has more protons, which pulls its electrons closer together, thus decreasing the overall size.
