What volume of helium would be in a balloon the size of a soft drink bottle
To calculate the volume of helium required to fill a balloon the size of a soft drink bottle, we need to know the volume of the bottle and the density of helium.
1. Determine the volume of a typical soft drink bottle. Soft drink bottles come in various sizes, so it's important to know the specific bottle size you have in mind. Generally, soft drink bottles range from 330 mL (11.2 fl oz) to 2 liters (67.6 fl oz).
2. Look up the density of helium. The density of helium at standard conditions (0 degrees Celsius and 1 atmosphere of pressure) is approximately 0.1785 g/mL or 0.1785 kg/L.
3. Calculate the volume of helium needed. Multiply the volume of the soft drink bottle (in mL) by the density of helium (in g/mL) or (in L) by the density of helium (in kg/L). This will give you the volume of helium required to fill the balloon.
For example, let's assume you have a soft drink bottle with a volume of 500 mL:
Volume of helium = Volume of soft drink bottle (in mL) × Density of helium (in g/mL)
Volume of helium = 500 mL × 0.1785 g/mL
Volume of helium = 89.25 grams of helium
Alternatively, if you prefer to use liters:
Volume of helium = Volume of soft drink bottle (in L) × Density of helium (in kg/L)
Volume of helium = 0.5 L × 0.1785 kg/L
Volume of helium = 0.08925 kilograms of helium
So, to fill a soft drink bottle-sized balloon, you would need approximately 89.25 grams or 0.08925 kilograms of helium.
