Answer : The must be administered.
Solution :
As we are given that a vial containing radioactive selenium-75 has an activity of .
As, 3.0 mCi radioactive selenium-75 present in 1 ml
So, 2.6 mCi radioactive selenium-75 present in
Conversion :
Therefore, the must be administered.
Answer : The volume of 1 mole of and
gases are the same.
Solution: Given,
Moles of = 1 mole
Moles of = 1 mole
Moles of = 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of are more than the moles of
and
. So, the volume of
will be more.
And the moles of and
are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of and
gases are the same.
