So half life is the time taken for a sample to decay to half its original mass, its a constant and applies to any original mass, it could be 5g or 1kg, it will take the same amount of time for the original mass to half. In this case the half life is 3 days.
After 3 days the sample will be at half its original mass, now 50g.
Now we can treat the 50g as if its a new sample. After another 3 days (6 days in total) there will be half of 50g left, = 25g.
The internal energy of the ideal gas is zero
The change in internal energy for an isothermal process is zero.
An ideal gas has no interactions between particles, therefore no intermolecular forces.
pressure change at constant temperature does not change the internal energy.
Adiabatic throttling expansion has less work done and lower heat flow.
That lower the internal energy.
The temperature decreases during the adiabatic expansion
Hence the internal energy of the ideal gas is zero

Answer:
Explanation:
The solution of known concentration is expressed as molarity. Molarity is the mole fraction of solute (i.e. the dissolved substance) per liter of the solution, Molarity is also commonly called molar concentration.
Mathematically;
To copy and complete the road map from the given question, we have the following array:
Volume A (L)
↓
d. multiplied by the molarity of A
↓
moles A
↓
b. multiplied by the moles of B / moles of A
↓
moles B
↓
c. divided by the molarity of B
↓
volume B (L)
