The pressure of a piston with a volume of 650 cm3 and 85ºC is 830 mmHg. It is heated to 350ºC and compressed to a volume of 65 cm3. What is the new pressure?

34176.5 torr

Explanation:

It is given that :

Initial pressure, torr

Initial volume,

Initial temperature,  

Final volume,  

Final temperature,  

Therefore, using the combined gas laws, we can write :

Substituting the values, we get

    = 34176.5 torr

So the new pressure is 34176.5 torr.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
