Two solutions of different concentrations of acid are mixed creating 40 mL of a solution that is 32% acid. One-quarter of the solution is made up of a 20% acid solution. The remaining three-quarters is made up of a solution of unknown concentration, c. Which equation can be used to determine c, the unknown concentration? 30c 10(0. 2) = 40(0. 32) StartFraction 3 Over 4 EndFraction left-parenthesis c right parenthesis plus left-parenthesis StartFraction 1 Over 4 EndFraction left-parenthesis 0. 2 right-parenthesis right-parenthesis equals 40 times 0. 32. (c) StartFraction 1 Over 4 EndFraction cup. (0. 2) = 40(0. 32) (c)( (0. 2)) = 40(0. 32) 30(c)(10(0. 2)) = 40(0. 32).

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.
