Answer: 180torr

Explanation:

Using P1VI/T1= P2V2/T2

where

p1= 650 torr

p2=??

T1= 27°C =  27°C + 273= 300K

T2= -183°C= -183°C +273=90K

V1= V2 ie volume is constant

SOLUTION

 1 torr= 1mmHg

P1VI/T1= P2V2/T2, where V1=V2

= P1/TI= P2/T2

600/300=P2/90

P2= 600X90/300= 180 torr

According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products. The mass of products and reactants will only differ during a nuckear reaction
Changing of the physical state of water is not a nuclear reaction. So becoz of that the mass will remain constant without any change.
