The oxygen which will be consumed by a person in 1 week is 393.75 moles.
The ratio of a substance's given mass in a chemical reaction to the mass of one mole of that material is the number of moles of that substance. A mole of any substance is equal to 6.023 × 10²³ or Avogadro's number. Molecular weight and other concentration units like mole per liter are also expressed using it.
No. of moles = given mass of substance / Molar mass of a substance
here, given mass = 900g
molar mass = 16g
No. of moles = 900/16 =56.25 moles
This means that 56.25 moles are consumed by a person in 1 day
No. of moles of oxygen consumed in 1 week = 56.25 ×7 = 393.75 moles
