Web17 sep. 2024 · If we know mass, pressure, volume, and temperature of a gas, we can calculate its molar mass by using the ideal gas equation. Recall that the ideal gas equation is given as: PV = nRT. We can rearrange this equation in terms of moles (n) and then solve for its value. Once we get the value for moles, we can then divide the mass of gas by … Web31 mrt. 2024 · to calculate weight from mass. In this formula, = weight (in N), = mass (in kg), and = acceleration due to gravity (in m/s 2 ). Since weight is a force, scientists also write the equation as , where = force (in N), = mass (in kg), and = acceleration due to gravity (in m/s 2 ). The value of gravity, , is 9.8 m/s 2 on Earth.
