Answer:
There are typically three ways that it is accomplished: use of erythropoietin (EPO) or synthetic oxygen carriers and blood transfusions. While transfusions of large volumes of blood or use of EPO can be detected, microdosing EPO or transfusing smaller volumes of packed red blood cells is much harder to detect.
Use a calculator to add those thank you ur welcome
Because of its chemical structure.
The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator.
<h3 /><h3>What is indicator?</h3>
In science, a marker capability or a trademark capability of a subset An of a set X is a capability characterized from X to the two components set {0, 1}, normally signified as, and it demonstrates whether a component in X has a place with A. Markers are insights used to gauge current circumstances as well as to figure monetary or financial patterns. In the realm of money management, pointers regularly allude to specialized diagram designs getting from the value, volume, or open revenue of a given security. Markers are insights used to gauge current circumstances as well as to conjecture monetary or financial patterns. In the realm of money management, pointers normally allude to specialized graph designs getting from the value, volume, or open revenue of a given security.

From the Ideal gas law (Combined gas law)
PV/T = P'V'/T' .....eq 1
Where:
P - initial pressure
V - initial volume
T - initial temperature
P' - final pressure
V' - final volume
T' - final temperature.
To proceed we have to make T the subject from eq.1
Which is, T = P'V'T/PV.......eq.2
We have been provided with;
Standard temperature and pressure (STP)
P = 760 mm Hg (SP - Standard Pressure)
T = 273.15 K (ST - Standard Temperature)
V = 62.65 L
P' = 612.0 mm Hg
V' = 78.31 L
T' = ? (what we require)
Therefore, we substitute the values into eq.2
T' =
.
T' = 275.60 K
T = (275.60 - 273.15) ......To °C
T = 2.45 °C
