V = nRT / P = (4.53 mol) x (0.08205746 L atm/K mol) x (301 K) / (1.78 atm) = 62.9 L

Explanation:

According to ideal gas equation, product of pressure and volume equals n times R times T.

Mathematically,            PV = nRT

where         P = pressure

                   V = volume

                   n = number of moles

                   R = gas constant

                   T = temperature

Since, it is given that no. of moles is 4.53 mol, pressure is 1.78 atm and temperature is 301 K. Value of R will be 0.082 L atm K^{-1}mol^{-1} Therefore, calculate the volume as follows.

                                 PV = nRT

         1.78 atm \times V = 4.53 mol \times 0.082 L atm K^{-1} mol^{-1} \times 301 K

                              V = \frac{111.81 L atm}{1.78 atm}

                                  = 62.81 L

Thus, we can conclude that volume of hydrogen will be 62.81 L.

Answer:

3.41 x10⁶ torr

Explanation:

To solve this problem we need to remember the equivalency:

1 torr = 133.322 Pa

Then we can proceed to<u> convert 4.55×10⁸ Pa into torr.</u> To do that we just need to multiply that value by a fraction number, putting the unit that we want to convert <em>from</em> in the <em>denominator</em>, and the value we want to convert <em>to</em> in the <em>numerator</em>:

4.55x10⁸ Pa * \frac{1torr}{133.322Pa} = 3.41 x10⁶ torr

The nucleus of unstable _____ of an element will decay leading to emission of radiation.question 1 options:moleculescationsanion
Marta_Voda [28]

Isotopes of same element has different number of neutrons with different masses and having same number of protons and electrons.

Radioactive isotopes are those isotopes which are radioactive in nature. The unstable nucleus results in the radioactivity process and this process will go on until the stable isotope (element) forms.

Thus, the nucleus of unstable isotopes of an element will decay leading to emission of radiation.
