Answer:
1.27 × 10⁵ L
Explanation:
Step 1: Given data
- Initial pressure (P₁): 745 Torr
- Initial volume (V₁): 1.41 × 10⁴ L
- Inital temperature (T₁): 21 °C
- Final pressure (P₂): 63.1 Torr
- Final temperature (T₂): -48 °C
Step 2: Convert the temperatures to the Kelvin scale
We will use the following expression.
K = °C + 273.15
K = 21 °C + 273.15 = 294 K
K = -48 °C + 273.15 = 225 K
Step 3: Calculate the final volume of the balloon
We will use the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
V₂ = P₁ × V₁ × T₂/ T₁ × P₂
V₂ = 745 Torr × 1.41 × 10⁴ L × 225 K/ 294 K × 63.1 Torr
V₂ = 1.27 × 10⁵ L
Answer:
[Og] 5g2 6f3 8s2 8p1
Explanation:
Unbihexium, or element 126 is a hypothetical chemical element, until the element is discovered, confirmed and a permanent number is decided. This element is expected to be a g-block superactinide and the eight element in the 8th period.
Energy, mass, and the speed of light squared.
(E, M, and C^2 respectively).
Hope this helped! :)
Answer:
21 g/mL
Explanation:
To solve this problem, first look at the density equation, which is D=M/V, which D stands for density, M stands for mass, and V stands for volume. When you substitute in the variables, you get D=17.5/.82, which is equivalent to 21.34. However, since we need to pay attention to the sig fig rules for multiplying, we need to have the same amount of sig figs as the value with the least amount of sig figs, which is the number .82. .82 has two sig figs, so you round down. Your answer will be 21 g/mL.
It is called a watt and or wattage
