Stp Formula

In Chemistry, STP is an elementary concept. In the STP system, both pressure and temperature are in their typical form. Pressure and temperature of this system are considered as 760 torr and 273K correspondingly. You can compute the volume of gas in STP using the standard formula. In this standard formula, the pressure is in torr and temperature is in Kelvin. 

Volume at STP Formula 1
Pressure at STP Formula 1 =760 torr
Temperature at STP Formula 1 = 273K
STP Problems

Solved problems for gas in STP are provided below:

Solved Examples

Problem 1: Compute the volume of a gas at STP whose volume is 0.5L and the temperature and pressure are 300K and 700 torrs respectively?

Answer:

Given numerics are,

T = 300K

P = 700 torr

Volume of the gas = 0.5L

Formula for volume of a gas at STP is,

Volume at STP Formula 2

Volume at STP Formula 3

Volume at STP Formula 4=4.190L

Problem 2: At 350 K and 1100 Torr the volume of a gas is 30L. Compute the volume of this gas at STP?

Answer:

The numerics known to us are,

T = 350K

P = 1100 torr

Volume of the gas = 30L

for the volume of gas in the STP the formula is,

Volume at STP Formula 5

Volume at STP Formula 7

Volume at STP Formula 9 = 33.868L
