A sample of helium gas at 841 mmHg and 14.7°C is heated to 84.7°C at constant volume. Calculate its final pressure (in atm). atm. Do NOT enter unit. Report your final answer with 3 SFs.

1.38

Explanation:

Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

    (At constant volume and number of moles)

where,

= initial pressure of gas  = 841 mm Hg

= final pressure of gas  = ?

= initial temperature of gas  =  

= final temperature of gas =  

   ( 760 mm Hg = 1atm )

Thus the final pressure is 1.38

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
