<h3>
Answer:</h3>
134 atm
<h3>
Explanation:</h3>
- Based on the pressure law, the pressure of a gas varies directly proportionally to the absolute temperature at a constant volume.
- Therefore; we are going to use the equation;
In this case;
Initial pressure, P1 = 144 atm
Initial temperature, T1 (48°C) = 321 K
Final temperature, T2 (25°C) = 298 K
We need to find the final pressure,
Therefore;
P2 = (P1/T1)T2
= (144/321)× 298 K
= 133.68 atm
= 134 atm
Therefore, the new pressure will be 134 atm.
Answer:
6.0 L
Explanation:
For this question, we can use
P1×V1= P2 × V2
where
P1 (initial pressure)= 0.2 kPa
V1 (initial volume)= 15L
P2 (final pressure)= 0.5 kPa
V2(final volume)= ?
Since we are trying to find final volume, we can rearrange the equation to make V2 the subject.
V2= (P1 × V1)/ P2
V2= (0.2 ×15)/0.5
V2 =6 L
Answer:
53.87g
Explanation:
Given parameters:
Percentage by mass of Nitrogen in fertilizer = 19%
Mass of fertilizer = 10.0oz
Unkown:
Mass in grams of Nitrogen in the container = ?
Solution
To solve this problem, we first find the percentage of mass of nitrogen in the fertilizer by a taking a percentage of the given mass of the fertlilizer:
Mass of Nitrogen in ounces of the fertilizer =
x 10 = 1.9oz
Since we are expected to express this in grams:
1oz = 28.35g
1.9oz = 1.9 x 28.35, 53.87g
