NTP Full form in Chemistry, Medical and Engineering

NTP Full form in Chemistry

You may haven often seen this abbreviationNTP in the field of chemistry, medical and engineering thermodynamics. The NTP full form is normal temperature pressure condition and is defined as air at 20°C (293 k ) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 407 in H2O, 760 torr). Density 1.204 kg/m3 (0.075 pounds per cubic foot)

Under these conditions the volume of air or any gas (also called molar volume) at 1 mol is 24.0548 liters

Example 1

Calculate the volume of 0.223 moles of nitrogen at NTP

Solution:

At NTP condition, 1 mol of nitrogen at P =1 atm and T= 293 K occupies 24.0548 liters

So, Volume of 0.223 moles of Nitrogen = 24.0548 * 0.223 = 5.3642 liters  

 

Example 2

Calculate the moles of 5.37 liters of nitrogen at NTP condition

Solution:

The molar volume of Nitrogen at NTP condition = 24.0548 liters

So,

Moles of Nitrogen at NTP = 5.37 / 24.0548 = 0.223 moles
