Sea level because air a much thinner at higher altitudes
The moles of phosphorous which are present in 750 grams of phosphorous is 24.27 moles.
<h3>What is the relation between mass & moles?</h3>
Relation between the mass and moles of any substance will be represented as:
- n = W/M, where
- W = given mass
- M = molar mass
Moles of phosphorous which are present in 750 grams will be calculated as:
n = 750g / 30.9g/mol = 24.27 moles
Hence the resultant moles of phosphorous is 24.27 moles.
