The mass of an exoplanet is typically determined using methods such as the radial velocity technique, where the gravitational pull of the planet causes measurable wobbles in its host star's motion. Another method is the transit method, which measures the amount of starlight blocked when a planet passes in front of its star, allowing calculations of the planet's size and density. By combining these data, scientists can estimate the mass of the exoplanet. The mass is often expressed in relation to Earth's mass (e.g., in Earth masses or Jupiter masses).

When calculating an atomic approximate mass how is the mass of electron figured?

When calculating the atomic mass of an atom, the mass of an electron is typically considered negligible. This is because the mass of an electron is almost 2000 times smaller than the mass of a proton or neutron, which are the primary components used in determining the atomic mass of an atom.

Formula for calculating mass?

The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).


What is the formula for calculating the linear mass density of a one-dimensional object?

The formula for calculating the linear mass density of a one-dimensional object is mass divided by length. It is represented as m/L, where is the linear mass density, m is the mass of the object, and L is the length of the object.


What is the equation used for calculating density?

density = mass/volume
