What is the mass of 2.50L of SO2 gas at stp
2 answers:
Answer: 4.84 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass, occupies 22.4 L of volume at STP and contains avogadro's number of particles.
To calculate the number of moles, we use the equation:
1 mole of weighs = 44 g
0.11 moles of weigh =
Thus mass of 2.5 L of weigh 4.84 grams.

Answer and Explanation:
For the following balanced reaction:
PCl₅(g) ↔ PCl₃(g) + Cl₂(g)
We can see that all reactants and products are gases, so it is an homogeneous equilibrium. The expression for the equilibrium constant Kp can be written from the partial pressures (P) of reactants and products as follows:
Where PPCl₃ is the partial pressure of PCl₃ (reactant), PCl₂ is the partial pressure of Cl₂ (reactant) and PPCl₅ is the partial pressure of PCl₅ (product).
Answer:
A. your running speed 1.5 m/s
B. your mass 70 kg
C. your de Broglie wavelength m
Explanation:
Hello there!
In this case, since the equation for the calculation of the Broglie wavelength is:
We can assume a running speed of about 1.5 m/s and a mass of 70 kg, so the resulting Broglie wavelength is:
