Answer:
it’s mass was greater than when it started
Explanation:
When a metal is coated with another metal, the plating metal deposits on the plated metal. Usually, the plating metal functions as the anode while the plated metal functions on the cathode. The anode metal is oxidized and reduced at the cathode and become deposited on the cathode material. This increases the mass of the cathode. Hence the mass of the silver/gold product is greater than the mass of silver at the beginning of the electroplating process.

Answer:
V2= 625 cm^3
Explanation:
P1 × V1 = P2 × V2
P1 (initial pressure)=125 kPa
V1 ( initial volume)= 450 cm^3
P2 (final pressure)=90kPa
V2 (final volume)= ?
Rearrange the equation to make V2 the subject, since it is the value we are trying to find
V2=(P1 × V1)/P2
V2= (125 ×450)/90
V2= 625 cm^3
