Scorpion4ik [409]

Answer:

volume = 972.23ml

Explanation:

using general gas law

P1V1/T1 = P2V2/T2

765 x 585/293 = 443 x V2/282

1527.39 =443 x V2/282

1527.38 x 282 = 443 x V2

430695.78 = 443 x V2

V2 = 430695.68/443

V2 = 972.23mL

The density of mercury, the only metal to exist as a liquid at room temperature, is 13.6 g/cm3. What is that density in pounds p
saw5 [17]

Answer:

0.492 lb/in^3

Explanation:

From Density of Mercury (13.6g/cm3) given,

Mass = 13.6g

Volume = 1cm3

Now we covert these variables as follows :

For Mass:

454 g = 1 lb

13.6g = 13.6/454 = 0.03lb

For volume:

2.54 cm = 1 in

1cm = 1/2.54 = 0.394in

Volume = (0.394in)^3 = 0.061 in^3

Density = Mass /volume

Density = 0.03lb/0.061 in^3

Density = 0.492 lb/in^3
