If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The units for density will be g/cm³. Arrangement of atoms in different metals is similar.
The density of an object or a substance is its mass, divided by its volume. We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. For example ...
The inflow and outflow are one-dimensional, so that the velocity V and density \rho are constant ... statement of the principle of mass conservation for a steady, one-dimensional flow, with one inlet ...
