Question

the partial pressure of argon in the atmosphere is \\(0.946\text{ kpa}\\). calculate the partial pressure in \\(\text{atm}\\).
be sure your answer has the right number of significant digits.

Explanation:

⚡ Using what you learned: Unit Conversions

Step 1: Identify conversion factor

$$ 1\text{ atm} = 101.325\text{ kPa} $$

Step 2: Convert pressure to atm

$$ 0.946\text{ kPa} \times \frac{1\text{ atm}}{101.325\text{ kPa}} \approx 0.0093363\text{ atm} $$

Step 3: Round to significant digits

The given value \(0.946\text{ kPa}\) has \(3\) significant digits.

$$ 0.0093363\text{ atm} ightarrow 0.00934\text{ atm} \text{ or } 9.34 \times 10^{-3}\text{ atm} $$

Answer:

\(0.00934\) (or \(9.34 \times 10^{-3}\))
