Respuesta :
At STP, the volume of oxygen of mass 250g is found to be 175mL.
Volume is the amount of space occupied by an item or substance. Volume is a measurement of how much 3-dimensional space an object occupies. Volume is the measurement of a limited quantity of area at a specific end.
Mass is a measurement of the quantity of matter in an item or substance. Mass is the physical quantity that represents the amount of matter in an object's body. The amount of weight accommodated in an item or stuff is measured in mass.
Density - The amount of space taken up by an item or substance (its volume) in proportion to the amount of matter in that thing or substance (its mass).
Given:
Mass = 250g = 0.25kg
Density at STP = 1.4291g/L
To find:
Volume = ?
Formula:
Density = Mass / Volume
Calculations:
Volume = Mass / Density
Volume = 0.25 / 1.4291
Volume = 0.175L
Volume = 175mL
Result:
The volume of oxygen of mass 250g is found to be 175mL at STP.
