The volume of blood plasma in adults is 3.1 L. it's density is 1.03 g/cm3. Approximately how many pounds of blood plasma are there in your body?

Sagot :

The important thing in this question is the unit. The mass equals density * volume. 3.1 L = 3.1 * 10^3 cm3. So the mass is 3.193*10^3 g. 1 pound = 453.95 g. So the answer is 7.04 pounds.

There are 7.039 pounds of blood plasma in your body

Further explanation  

7 main quantities have been determined based on international standards, namely:  

  • 1. Length, meters (m)
  • 2. Time, second (s)
  • 3. Mass, kilograms (kg)
  • 4. Temperature, kelvin (K)
  • 5. Light intensity, candela (cd)
  • 6. Electric current, amperage (A)
  • 7. Amount of substance, mol (m)

Mass is one of the principal quantities, which is related to the matter in the object  

The main mass unit consists of 7 units :

  • Kilogram, kg  
  • Hectogram, hg  
  • Decagram, dag  
  • gram, g  
  • Decigram, dg  
  • centigram, cg  
  • milligrams, mg  

Each unit descends then multiplied by 10, and if one unit increases then divided by 10  

Conversion of other mass units:  

mg milligrams = 10⁻³ g  

kg kilograms = 10³ g  

µg micrograms (mcg) = 10⁻⁶ g  

Mg megagrams (tons) = 10 g  

ng nanograms = 10⁻⁹ g  

Gg gigagram = 10⁹ g  

ρg picogram = 10⁻¹² g  

1 pounds = 0.4536 kg

For volume of blood plasma = 3.1 L and

ρ = density = 1.03 g/cm³ = 1.03 kg/l

then :

mass of blood plasma = density x volume

mass = 1.03 kg/l x 3.1 L = 3.193 kg

3.193 kg into pounds become :

3.193 kg :  0.4536  = 7.039 pounds
