Answer:
B
Explanation:
Carbon Dioxide is one of waste produced from Our cells during respiration. The circulatory system carries Carbon Dioxide from cells either in haemaglobin in RBC or plasm. The Carbon Dioxide being carried to blood cappilaries near alveoli before diffused into alveoli and then being removed away by respiratory system in the process of respiration while we exhale
We have that
The average atomic mass round and to the second decimal place (0.01) is
A_m=126.90
From the question we are told
Find the average atomic mass round and to the second decimal place (0.01)
80% 127I, 17% 126I, 3% 128I
Generally the equation for the Average Mass is mathematically given as
Where
a1 = 127
b1 = 80%
a2 = 126
b2 = 17%
a3 = 128
b3 = 3%
Therefore
In conclusion
The average atomic mass round and to the second decimal place (0.01) is
A_m=126.90

Answer:
2117.02 litres
Explanation:
Using the ideal gas equation as follows;
PV = nRT
Where:
P = pressure of the gas (atm)
V = volume of the gas (L)
n = number of moles (mol)
R = gas law constant (Latm/molK)
T = temperature (K)
According to the information given in this question,
P = 0.12 atm
V = ?
n = 9.7moles
T = 46°C = 46 + 273 = 319K
R = 0.0821 Latm/molK
Using PV = nRT
0.12 × V = 9.7 × 0.0821 × 319
0.12V = 254.04
V = 254.04 ÷ 0.12
V = 2117.02 litres
