70 torr will be same as which of the following

Options

A. 9332.0325 Pa
B. 70 mm Hg
C. 0.0933 bar
D. All of these

Answer

To solve the question "70 torr will be the same as which of the following?", we will perform a series of conversions from torr to other units of pressure.

### Step-by-Step Solution:

**Step 1: Convert Torr to Atmospheres**
- We know that 1 atmosphere (atm) is equal to 760 torr.
- To convert 70 torr to atmospheres, we use the formula:
\[ \text{Pressure in atm} = \frac{\text{Pressure in torr}}{760} \]
- Substituting the value:
\[ \text{Pressure in atm} = \frac{70}{760} \approx 0.0921 \text{ atm} \]

**Step 2: Convert Atmospheres to Pascals**
- We know that 1 atmosphere is equal to \(1.01325 \times 10^5\) Pascals (Pa).
- Now, we convert 0.0921 atm to Pascals:
\[ \text{Pressure in Pa} = 0.0921 \times 1.01325 \times 10^5 \approx 9332.03 \text{ Pa} \]

**Step 3: Convert Atmospheres to Millimeters of Mercury (mm Hg)**
- We know that 1 atmosphere is equal to 760 mm Hg.
- To convert 0.0921 atm to mm Hg:
\[ \text{Pressure in mm Hg} = 0.0921 \times 760 \approx 69.996 \text{ mm Hg} \]
- This rounds to approximately 70 mm Hg.

**Step 4: Convert Atmospheres to Bars**
- We know that 1 atmosphere is equal to 1.01325 bars.
- Now, we convert 0.0921 atm to bars:
\[ \text{Pressure in bar} = 0.0921 \times 1.01325 \approx 0.0933 \text{ bar} \]

### Conclusion:
From the calculations above:
- 70 torr is approximately equal to 9332.03 Pa, 70 mm Hg, and 0.0933 bar.
- Therefore, all the conversions provided in the options are correct.

### Final Answer:
All the given conversions are correct.
