Mass of vaporized triethylamine : 2.606 g
<h3>Further explanation</h3>
Given
0.5 L triethylamine
P = 18.5 psi
T = 25 °C
Required
mass of vaporized triethylamine
Solution
Conversion :
P 18.5 psi = 1,26 atm
T = 25 +273 = 298 K
Ideal gas law :
PV=nRT
n = PV/RT
Input the value :
n = (1.26 atm x 0.5 L) /(0.08205 x 298)
n = 0.0258
MW triethylamine = 101 g/mol
Mass triethylamine :
= n x MW
= 0.0258 x 101 g/mol
= 2.606 g
<h3><u>Answer;</u></h3>
10 percent
<h3><u>Explanation;</u></h3>
- Probability is a number that describes how likely it is that an event will occur.
- In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
- Therefore; as a percentage;
1/10 × 100 = 10 percent
- Hence; The probability of each individual event occurring is 10 percent
