Answer:
10.8 L
Explanation:
Step 1: Given data
- Initial volume of helium (V₁): 595 L
- Initial pressure of helium (P₁): 1.00 atm
- Final volume of helium (V₂): ?
- Final pressure of helium (P₂): 55.0 atm
Step 2: Calculate the final volume of helium
If we assume ideal behavior and constant temperature, we can calculate the final volume of helium using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 1.00 atm × 595 L / 55.0 atm = 10.8 L
Answer:
This involves metric conversion and one can easily use dimensional analysis, assuming you know the conversion factors.
1 ng = 10-9 g, or put another way 109 ng = 1 g
1 kg = 103 g
5.27x10-13 kg x 1 g/1x10-3 kg x 1x109 ng/g = 5.27x10-1 ng = 0.527 ng
Looking at the individual steps and following the units, we have...
5.27x10-13 kg x 1 g/1x10-3 g = 5.27x10-10 g (kg cancel leaving g)
5.27x10-10 g x 1x109 ng/g = 5.27x10-1 ng = 0.527 ng (g cancel leaving ng)
Answer:
