The average density of human blood is 1.06 g/mL. What is the mass of blood in an adult with a blood volume of 5.5L? Express your
2 answers:
Answer : The mass of human blood in grams and ounce are 5830 grams and 205.647 ounce.
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used for density :
Given :
Density of human blood = 1.06 g/mL
Volume of human blood = 5.5 L = 5500 mL
conversion used : 1 L = 1000 mL
Now put all the given values in the above formula, we get the mass of human blood.
The mass of human blood in grams = 5830 grams
Conversion used :
As,
So,
Therefore, the mass of human blood in grams and ounce are 5830 grams and 205.647 ounce.

Answer:
36.37% is the percent yield of the reaction.
Explanation:
1)0.650 L nitrogen gas , at 295 K and 1.01 bar.
Let the moles of nitrogen gas be n.
Pressure of the gas ,P= 1.01 bar = 0.9967 atm (1 bar = 0.9869 atm)
Temperature of the gas = T = 295 K
Volume of the gas = V = 0.650 L
Using an ideal gas equation:
2) Moles of ammonia gas=
Moles of oxygen gas =
According to reaction ,3 mol of oxygen reacts with 4 mol of ammonia.
Then,0.1101 mol of oxygen will react with:
of ammonia.
Hence, oxygen gas is in limiting amount and act as limiting reagent.
3) Theoretical yield of nitrogen gas :
According to reaction, 3 mol of oxygen gas gives 2 moles of nitrogen gas.
Then 0.1101 mol of oxygen will give:
of nitrogen.
Theoretical yield of nitrogen gas = 0.0734 mol
Experimental yield of nitrogen as calculated in part (1) = 0.0267 mol
Percentage yield:
Percentage yield of the reaction:
36.37% is the percent yield of the reaction.
