Answer:
Mass = 121 g
Explanation:
Given data:
Mass in gram of CO₂ = ?
Volume = 61.8 L
Pressure = standard = 1 atm
Temperature = 273.15 K
Solution:
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm × 61.8 L = n ×0.0821 atm.L/ mol.K × 273.15 k
61.8 L.atm = 22.42 atm.L/ mol × n
n = 61.8 L.atm /22.42 atm.L/ mol
n = 2.76 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 2.76 mol × 44 g/mol
Mass = 121 g
The mole ratio between sodium bicarbonate and that of acetic acid is 1:1
<h3>What is mole ratio?</h3>
A mole ratio can be defined as that ratio in whole numbers between the amounts in moles of any two compounds involved in a balanced chemical reaction.
- The mole ratio of each individual element is found by dividing the number of moles of each by the smallest number of moles.
In conclusion, the mole ratio between sodium bicarbonate and that of acetic acid is 1:1

Answer: why do I think that water boils when the vapor pressure is equal to the atmospheric pressure?
because The pressure level of a liquid lowers the number of pressure exerted on the liquid by the atmosphere. ... pressure level may be increased by heating a liquid and causing more molecules to enter the atmosphere. At the purpose where the pressure level is up to the air pressure boiling will begin.
