What is the density of O2 at STP?

Answer 1

Using the National Institute of Standards and Technology STP of 20 °C (293.15 K, 68 °F) and an absolute pressure of 101.325 kPa (14.696 psi, 1 atm), the density of water is 998.2071kg/m3.

Answer 2

To find the density of N2O at STP, you need to use the formula that density is equal to mass divided by the volume. At STP, one mole of N2O has a mass of 44 grams, and the volume is 22.4 liters. Dividing these two quantities, one find the answer as 1.96 g/l.

Answer 3

kv = -1.1555 x 10^(-14) x T^3 +9.5728 x 10^(-11) x T^2 + 3.7604 x 10^(-8) x T - 3.4484 x 10^(-6)

Where

kv is kinematic viscosity in M2/sec

T is in K

The above equation is valid from T = 100 to 1600 K.

Answer 4

At 300 degrees Fahrenheit and atmospheric pressure the air:

Dynamic Viscocity (μ) : 4.97 x 10-7 (lbf s/ft2)

Kinematic Viscocity (v) : 3.06 x 10-4(ft2/s)

Some conversion factors for viscocity:

• 1 N s/m2 = 1 Pa s = 10 poise = 1,000 milliPa s
• 1 m2/s = 1 x 104 cm2/s =1 x 104 stokes = 1 x 106 centistokes

Answer 5

The density of O2 at standard temperature and pressure (STP: 0°C and 1 atm) is approximately 1.429 g/L.

Answer 6

The density of dry air at STP (1 atm, 273 K) is 1.293 kg/m3.

Answer 7

STP is measured at 273 Kelvin and one atmosphere. At standard temperatures and pressures, O2 has a density of 1.429 grams per liter.

Answer 8

p= m/v

p= 32g/22.4cm3

p=1.43g/cm3
