**How do you find a number density?** Material density is given by ρ=m/V, where m is mass and V is volume. Again number density given by **n=N/V**, where N is the total number of particle.

**What is the number density of electrons in aluminum?** Find the drift speed of the electrons in the wire, assuming each aluminum atom contributes on electron. The density of aluminum is **2.7 g/cm **^{3}. I = nqv_{d}A. = 1.3 x 10^{–}^{4} m / s .

**What is the density of aluminum in g ml?**

**What is the density of aluminum in g m3?** The density of pure aluminum in solid form is **2,699 kg/m3** (theoretical density based on lattice spacing) and 2,697-2,699 kg/m3 (polycrystalline material). The liquid density of pure aluminum is 2,357 kg/m3 at 973K and 2,304 kg/m3at 1173K.

## How do you find a number density? – Additional Questions

### Why is aluminum Low density?

Aluminium has three electrons in its outer shell, and can form three bonds. Aluminium has a face-centered-cubic (fcc) structure which means the density is related to the cube of inter-atomic separation. **For element of similar atomic mass this arrangement results in lower densities.**

### Does the density of aluminum change?

Density of aluminum: **solid and liquid**

**With increasing temperature decreases density of aluminum**.

### How can you increase the density of aluminum?

1 Expert Answer. Nothing will happen to the density unless you **TURN THE HOT PLATE ON**. If you heat the aluminum it will expand and thus the density will decrease. This is the case because density = mass/volume and the mass remains the same but the volume invreased.

### Is aluminum the lightest metal?

**The first seven metals in the periodic table are lithium, beryllium, sodium, magnesium, aluminium, potassium and calcium, known collectively as the “lightest metals”**.

### What is the density of aluminum 6061?

The density of 6061 aluminum alloy is **2.7 g/cm3** (0.0975 lb/in3), or about the same as pure aluminum metal.

### What is the density of steel in kg m3?

That’s why the density of steel varies from **7750 kg/m3 to 8050 kg/m3**. But, steel is not the densest alloy or metal.

### What is the density of steel in g cm3?

**Carbon steel’s density is about 7.84 g/cm**^{3}, pure iron’s density is around 7.86 g/cm^{3}, and stainless steel’s is about 8.03 g/cm^{3}. The particular grade and chemical composition of the steel makes its density vary slightly.
