Ответ:
The patient B has strong blood clotting mechanism because its mass per unit volume is greater then patient A.
Density of patient A blood clot = 0.25 g/mL
Density of patient B blood clot = 0.33 g/mL
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of blood clot = 5 g
Volume of patient A blood clot = 20 mL
Volume of patient B blood clot = 15 mL
Densities = ?
Solution:
d (A) = m / v
d (A) = 5 g / 20 mL
d (A) = 0.25 g/mL
For patient B:
d (B) = m / v
d (B) = 5 g / 15 mL
d (B) = 0.3 g / mL
The patient B has strong blood clotting mechanism because its mass per unit volume is greater then patient A.
