Answer:
42 hours is 2520 minutes...
If 1000 mg drops in 2520 minutes,
Then in 1 minute, (1000/2520) drop drops...
Which is approximately 0.40 drops.
Which of the following describes a chemical property of oxygen
The total pressure of gases is equivalent to 739mmH divided by the area.
<h3>How to calculate the total pressure of gases?</h3>
To calculate the total pressure of gases, the next formula can be used:
- Total pressure: Force/area
- Total pressure 739 mmH/area
<h3>How to calculate the area?</h3>
The area of a cylinder is equal to 2πrh+2πr².
You can know the radio by checking the measurement of the base of the graduated cylinder. Also, you can determine the height by observing how many mm the gas is occupying. Then follow these steps:
- Find out the area based on the formula provided.
- Replace the area in the pressure formula.
- Solve the formula.
Note: This question is incomplete because the height occupied by the gas and the radio of the cylinder are not provided. Due to this, I answered this question based on general knowledge.
