Answer:
121.5 L will be the new volume
Explanation:
To solve this we can use the Ideal Gases Law
P . V = n . R . T for the two situations. But the moles of gas in the balloon are always the same so:
P . V / R .T = P . V / R. T
R is a universal constant, we can reject it. So:
P₁ . V₁ / T₁ = P₂ . V₂ / T₂
We also need to convert T° C to T°K → T°C + 273
30°C + 273 = 303 K and -48°C + 273 = 225K
Let's replace → (50.4L . 100 kPa) / 303K = (30.8 kPa . V₂) / 225K
((50.4L . 100 kPa) / 303K ) . 225K = 30.8 kPa . V₂
3742.5 kPa . L = 30.8 kPa . V₂
3742.5 kPa . L / 30.8 kPa = V₂ → 121.5 L
Answer:
0.0250 g.
Explanation:
∵ no. of moles (n) = mass / molar mass.
<em>∴ mass of Vitamine C = (n)(molar mass)</em> = (0.000142 mol)(176.12 g/mol) = 0.02501 g = <em>0.0250 g. "three significant figures"</em>
Answer: A diamond is a heterogeneous mixture. But it could be considered a element because it is made out of carbon which is an element.
Explanation:
Hey there!:
Ksp =(Mg⁺²)(2F⁻)²
Ksp = (1.18*10⁻³)(2*1.18*10⁻³)²
Ksp = 6.57*10⁻⁹
Hope that helps!
Answer:
The number of collisions is independent of volume.
