Question

The pressure of gas is measured as 49torr . represent this in pressure in both atmospheric and pascal

Answer 1

To convert the pressure from torr to atmospheres (atm) and pascals (Pa), you can use the following conversions:

1. **Torr to Atmospheres**:
\[
1 \text{ atm} = 760 \text{ torr}
\]
So, to convert 49 torr to atm:
\[
\text{Pressure in atm} = \frac{49 \text{ torr}}{760 \text{ torr/atm}} \approx 0.0645 \text{ atm}
\]

2. **Torr to Pascals**:
\[
1 \text{ torr} \approx 133.322 \text{ Pa}
\]
So, to convert 49 torr to Pa:
\[
\text{Pressure in Pa} = 49 \text{ torr} \times 133.322 \text{ Pa/torr} \approx 6526.79 \text{ Pa}
\]

In summary:
- Pressure in atmospheres: **0.0645 atm**
- Pressure in pascals: **6526.79 Pa**
