The volume of a gas can be found by using ideal gas formula. The formula would be:
V= nRT/P
where
n= number of the molecule (mol)
R= constant
T= temperature
P= pressure
Then, the answer would be
<span>1. temperature
2. pressure
3. mass
4. number of molecules </span>
Answer:
CH3CHCHCOOH : 11 sigma and 2 pi bonds
HCCCH2CHCHNH2: 12 sigma and 3 pi bonds
H2CCHCH2CCH: 10 sigma and 3 pi bonds
Explanation:
>In this carboxylic acid there are 11 sigma bonds between C-H, C-C ,C-O and O-H atoms,while there are two pi bonds ,one is made by carbonyl carbon and other from alkene C=C carbons
> In this amine there are 12 sigma bonds made by C-C,C-H and N-H atoms,while 2 pi bonds made by alkyne carbons C≡C carbons and 1 pi bond is made by alkene C=C carbon atoms
>In this organic molecule there are 10 sigma bonds made by C-C and C-H bonds ,while 2 pi bonds made by alkyne carbons C≡C carbons and 1 pi bond is made by alkene C=C carbon atoms.

¡Hola!
En este caso, como podemos observar, la relación entre la rapidez de reaction, las moles y el tiempo de reacción es:
De este modo, despejamos el tiempo en esta ecuación para obtener:
Así, reemplazamos la rapidez y moles dadas para obtener:

Answer:
The van't Hoff factor is 2.55
Explanation:
Step 1: Data given
Osmotic pressure of CaCl2 = 0.585 atm
Osmotic pressure of urea = 0.237 atm
Concentration = 9.69 * 10^-3 M
Temperature = 25.0 °C
Step 2:
Π = iMRT
⇒ with Π = the osmotic pressure of CaCl2 = 0.585 atm
⇒ with i is the van't Hoff factor
⇒ with M = the molar concentration = 9.69 * 10^-3 M
⇒ with R = the gas constant = 0.0821 L*atm/mol*K
⇒ with T = the temperature = 25.0 °C = 298 K
0.605 atm = i(9.69 * 10^-3 M)(0.0821 L*atm/mol*K)(298K)
i = 2.55
The van't Hoff factor is 2.55
