Answer:
4.33 L
Explanation:
Step 1: Given data
Initial volume of the balloon (V₁): 3.00 L
Initial pressure of the balloon (P₁): 765 torr
Final volume of the balloon (V₂): ?
Final pressure of the balloon (P₂): 530 torr
Step 2: Calculate the final volume of the balloon
If we consider Helium to behave as an ideal gas, we can calculate the final volume of the balloon using Boyle's law.

1. carbon lies in the 2nd period where silicon in the third period.
2. carbon is a non metal whereas silicon is a metalloid.
3. there are only 3 isotopes of carbon and 23 isotopes of silicon
4. size of silicon atom is larger
5. silicon is heavier than carbon.
Answer:
volume of box is 38.81 cm³.
Explanation:
Given data:
Width of box = 4.5 cm
Height of box = 5.750 cm
Length of box = 1.50 cm
Solution:
Formula:
Volume = length × height × width
by putting values,
V = 1.50 cm × 5.750 cm× 4.5 cm
V = 38.81 cm³
Thus, the volume of box is 38.81 cm³.
The answer is d. hope it helps
