They will melt at the same rate because they contain the same matter
hope this helps and good luck on your project!!!!
<span>Let's </span>assume that the gas is an ideal gas. Then we can use ideal gas equation,<span>
PV = nRT<span>
</span>Where,
P = Pressure of the gas (Pa)
V = volume of the gas (m³)
n = number of moles (mol)
R = Universal gas constant (8.314 J mol</span>⁻¹ K⁻¹)<span>
T = temperature in Kelvin (K)
<span>
The given data for the </span></span>gas is,<span>
P = ?
V = 9.5 L = 9.5 x 10</span>⁻³ m³<span>
T = (273 + 20) K = 293 K
R = 8.314 J mol</span>⁻¹ K⁻¹<span>
n = 1.2 mol
by applying the formula,
P x </span>9.5 x 10⁻³ m³ = 1.2 mol x 8.314 J mol⁻¹ K⁻¹ x 293 K
<span> P = 307705.5 Pa
P =3.08 x 10</span>⁵ Pa
<span>
Hence, the pressure of the gas is </span>3.08 x 10⁵ Pa.<span>

The fumes of acetic acid go to the floor instead of ceiling.
The reason behind the answer is that the density of acetic acid fumes is higher than the density of air (almost twice) that is equal to only 1
.
Thus, the fumes of acetic acid go to the floor.
C. The number of moles of a dissolved substance
