The question is whether green bugs or bright red bugs get eaten more often
Answer:
A
Explanation:
it is no longer going to unripen/ went through a chemical reaction
Answer:
The correct answer is 0.089 g/L ≅ 0.09 g/L
Explanation:
Density is defined as: mass/volume.
From the problem we have:
number of moles = n = 3 mol
volume = V = 67.20 L
We have to calculate the mass. For this, we need the molar mass (MM) of the gas. That is easily calculated from the molar mass of the element hydrogen (H), as we know that hydrogen gas has the molecular formula H₂:
MM(H₂) = 2 x molar mass H = 2 x 1 g/mol = 2 g/mol
Now, we multiply n by MM to obtain the mass (m) of the gas:
m = n x MM(H₂) = 3 mol x 2 g/mol = 6 g
Finally, we calculate the density from the mass and volume:
density = m/V = 6 g/(67.20) = 0.089 g/L ≅ 0.09 g/L
Moles of oxygen = mass/molar mass of O2 = 8/31.998 = 0.25 moles.
Number of particles = moles x 6.02 x 10^23 = 0.25 x 6.02 x 10^23 = 1.505 x 10^23 particles.
Hope this helps!
