# How do you find a number density?

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 = nqvdA. = 1.3 x 104 m / s .

What is the density of aluminum in g ml?

2.70

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/cm3, pure iron’s density is around 7.86 g/cm3, and stainless steel’s is about 8.03 g/cm3. The particular grade and chemical composition of the steel makes its density vary slightly.
