Answer 1

Standard temperature and pressure are the conditions that are considered standard when compared to experimental measurement. At STP, 6680 mL of oxygen will have 0.3 moles.

What is STP?

STP is the abbreviated form standard temperature and pressure that is a definitive condition of the reaction system that is used for the comparative analysis.

Given,

Volume of oxygen = 6680 mL = 6.680 L

At STP,

1 mol = 22.4 L

Substituting values to calculate the moles as

1 mol = 22.4 L

X mol = 6.680 L

Solving for X:

X = 6.680 L × 1 mol ÷ 22.4 L

= 0.298 moles

Therefore, 6680 mL of oxygen sample contains 0.3 moles of oxygen.
