12 formula 1 point
how many moles are in 21.1l of nitrogen gas at stp?
round your answer to two decimal places.
answer

Explanation:

Step1: Recall STP molar volume

At STP, 1 mole of gas = 22.4 L

Step2: Calculate volume for Q11

$\text{Volume} = 5.0 \times 22.4 = 112.00$ L

Step3: Calculate moles for Q12

$\text{Moles} = \frac{21.1}{22.4} \approx 0.94$

Answer:

1. 112.00 L
2. 0.94 moles
