## How do you find the density of oxygen?

m/V = (MMP)/(RT) = density of the gas. Now we need to insert the values we know. T = 27 °C, but we need absolute temperature. Answer: The density of the oxygen gas is 6.5 g/L.

**What is the formula for calculating density of gas?**

To find density, we have to solve the equation for volume, or V. V = nRT / P. To incorporate mass, we can use the number of moles, or n. The number of moles equals the mass of the gas divided by the molecular mass.

**How do you convert density to mass and volume?**

User Guide

- Formula. The formula used by this calculator to determine mass from volume and density is: m = V x ρ Symbols. m= Mass. V = Volume.
- Volume Measured. Enter volume of the object and select the appropriate volumetric units.
- Density of Substance. Enter the known density of the material being measured.
- Mass Calculation.

### What is the density standard for gases?

The official IUPAC unit for gas density is kg/m3 (not g/L). However, it turns out that one kg/m3 equals one g/L. Here is a brief video explaining the conversion. One place teachers like to bring gas density into play is when you calculate a molar mass of a gas using PV = nRT.

**What is density of oxygen?**

**How is the density of the earth calculated?**

Some assorted numbers given would be: 5.5, 5.52, and 5.15 g/cm 3 (estimations that are made can change the outcome of a calculation). Density is found by dividing the mass by the volume (ρ = m/V). A scientist named Henry Cavendish is known for calculating the mass (and then density) of the Earth.

## How do you find the mass of the Earth?

Now, to find the radius, divide the diameter by 2 (because any radius is exactly half of its diameter). The mass of the Earth is found to be 6 sextillion, 587 quintillion short tons (or 5.98 × 10 21 metric tons). Since the Earth is a sphere, the formula 4/3πr 3 is used to find the volume.

**Which is the correct formula for the volume of the Earth?**

Since the Earth is a sphere, the formula 4/3πr 3 is used to find the volume. The volume of the Earth is considered to be 1.08 × 10 12 km 3 (or 2.5988 × 10 11 miles 3).

**How do you find atomic radius given the density?**

We see that there is 1 atom per unit cell (1/8 “atom” at each corner) and that the edge length of the cell (a) is twice the atomic radius (r). The volume of one atom is V_”atom” = 4/3πr^3.
