A stock solution is a solution of a known concentration. Stock solution has a high concentration and therefore, the known amount of stock solution is used for preparing different concentrations, by diluting the same with the known amount of the solvent being used, such as water.
Answer:C
Explanation: The mass is still the same even though they took it apart.
The temperature will be 1200K if the volume remained constant
calculation
This is calculated using gay lussac law formula, that is P1/ T1=P2/T2 since the volume is constant
P1 = 100 Kpa
T1= 300 K
P2= 400 Kpa
T2=?
by making T2 the subject of the formula T2 =( P2 xT1)/P1
T2 is therefore = (400 KPa x 300 K) / 100 Kpa = 1200 K
