An electron weighs 1/1836 atomic mass unit and, on the other hand, an alpha particle weighs 4 atomic mass unit.
<span>4 amu / (1/1836 amu) = 7344 </span>
<span>Therefore, an alpha particle is 7344 times heavier than an electron.
Hope this answers the question. Have a nice day.</span>
That makes the Earth, the Sun, and the rest of the solar system
<span>something like 23 thousand times as old as the human species !

The partial pressure of the gas will be the total pressure minus the vapor pressure. 523.8-23.8=500mmHg. This makes sense due to the fact that the idea of partial pressures still works even with vapor pressure since vapor pressure is just the partial pressure of water vapor (23.8mmHg) in the container which is added to the partial pressure of hydrogen gas (500mmHg) to make a total pressure of 523.8mmHg.
I hope this helps. Let me know in the comments if anything is unclear.
Because it is one of the strongest chemicals and it is very dangerous.
