In order to prepare 250 mL of a 1.50 M solution of Ba(OH)₂ from solid Ba(OH)₂ , you would need: a graduated cylinder and mass balance
a beaker and 250 mL volumetric flask
a 250 mL volumetric flask and mass balance
a graduated cylinder and 250mL volumetric flask

the millers tale is the answer.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
