The density of o2 gas at 16 degrees Celsius and 1.27atm is?

The density of O₂ gas is 1.71

Explanation:

Density is a quantity that allows you to measure the amount of mass in a given volume of a substance. So density is defined as the quotient between the mass of a body and the volume it occupies:

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

So, you can get:

The relationship between number of moles and mass is:

Replacing:

So:

Knowing that 1 mol of O has 16 g, the molar mass of O₂ gas is 32 .

Then:

In this case you know:

Replacing:

Solving:

density= 1.71

The density of O₂ gas is 1.71

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
