percent by mass of carbon = 27,27 %
percent by mass of oxygen = 72.72 %
Explanation:
To calculate the percent composition of carbon dioxide (CO₂) we use the following algorithm.
Molecular mass of CO₂ = atomic weight of carbon × number of carbon atoms + atomic weight of oxygen + number of oxigen atoms
Molecular mass of CO₂ = 12 × 1 + 16 × 2 = 44 g / mole
Considering 1 mole of CO₂ we devise the following reasoning:
If in 44 g of CO₂ we have 12 g of carbon and 32 g of oxygen
Then in 100 g of CO₂ we have X g of carbon and Y g of oxygen
X = (100 × 12) / 44 = 27,27 % carbon
Y = (100 × 32) / 44 = 72.72 % oxygen

Answer:
Amplitude is measured from the center line to the highest point in the waves.
Wavelength is the distance between one wave to the other from the highest point.
Frequency is the rate of the waves.
