How many moles of chlorine gas at 120.0°C and 26.1 bar would occupy a vessel of 38.0 L? R = 0.08314 L･bar/mol･K.

The number of moles of chlorine gas at 120.0°C and 26.1 bar that would occupy a vessel of 38.0 L is 30.4moles.

HOW TO CALCULATE NUMBER OF MOLES:

Where;

T = 120°C + 273 = 393K

26.1 × 38 = n × 0.08314 × 393

991.8 = 32.67n

n = 991.8 ÷ 32.67

n = 30.4moles

n = 30.36 mol

Explanation:

Given data:

Temperature of gas = 120.0°C

Pressure of gas = 26.1 bar

Volume of gas = 38.0 L

Number of moles of Cl gas = ?

Solution:

Formula:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.08314 bar.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

120+273 = 393 K

26.1 bar ×38.0 L = n × 0.08314 bar.L/ mol.K   × 393 K

991.8 bar.L = n × 32.67bar.L/ mol

n = 991.8 bar.L/ 32.67bar.L/ mol

n = 30.36 mol

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
