Answer:

I believe it's 2.70 grams

Explanation:

First, divide 1.33 x 10^22 by 6.022 x 10^23. 6.022 x 10^23 is Avogadro's constant of 1 mole of any atoms. After you divide, you get 2.208568582 x 10^-2 which you should round the the nearest hundredth which is 2.21 x 10^-2. Second, because of Sb or Antinomy atomic mass is 121.760, round it up to the whole number which is 122. Therefore, multiply 122 and 2.21 x 10^-2 which it'll equal to 2.6962 x 10. Finally, round it up and you'll get 2.70 grams. Hope that helps!

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling of liquid will begin.

<h3>What happens when atmospheric pressure is equal to the vapor pressure of liquid?</h3>

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. The bubbles formation started to the liquid molecules which have gained enough energy to change to the gaseous phase.

The vapor pressure of ethanol is 5.95 kPa at 20.0 °C, and its vapor pressure is 53.3 kPa at 63.5 °C.
