Explanation:

The observation that can make the chemist conclude that the liquid is a pure substance is if the unknown liquid composition is the same at every point of sampling.

  • Pure substances are distinct substances.
  • They have a definite composition.
  • All the parts are the same throughout.
  • They cannot easily be separated or broken down into simpler substances by physical means.
  • They have a unique set of physical properties.

Therefore, if his analysis meets any of the criteria for defining a pure substance above, he can conclude that it is one.

Pure substances are elements and compounds.

How many moles of N2 are need to fill a 35 L tank at standard temperature and pressure?
Tems11 [23]

1.56 moles of N2 are needed to fill a 35 L tank at standard temperature and pressure. Details about moles can be found below.

<h3>How to calculate number of moles?</h3>

The number of moles of a substance can be calculated using the following formula:

PV = nRT

Where;

  • P = pressure
  • V = volume
  • n = number of moles
  • R = gas law constant
  • T = temperature

At STP;

  • T = 273K
  • P = 1 atm
  • R = 0.0821 Latm/molK

1 × 35 = n × 0.0821 × 273

35 = 22.41n

n = 35/22.41

n = 1.56mol

Therefore, 1.56 moles of N2 are needed to fill a 35 L tank at standard temperature and pressure.
