Explanation:
The solvent is a base or medium , in which reaction takes place ,
Mostly organic solvents have hydrogen and carbon , and is purposely used to dissolve the organic sample .
The example of organic solvents , used in laboratory are as follows -
1. Toluene
2. Hexane
3. Pentane
4. Benzene
5. Methanol
Answer:
4g/cm^3
Explanation:
The formula for density is mass divided by volume. 180g is your mass, 45cm^3 is your volume, divide the two to get your answer.
Answer:
The temperature at 760mmHg if the volume is still 4.2 L is 400.862 K
Explanation:
Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:

Having an initial state 1 and a final state 2, the following is true:

In this case:
- P1= 560 mmHg
- T1= 72 F= 295.372 K (being 32 F= 273.15 K)
- P2= 760 mmHg
- T2= ?
Replacing:

Solving:

T2= 400.862 K
