If the barometer reading is too high, the molar mass of the compound will be too low. If the barometer reading is too low, the molar mass of the compound will be too high.
The molar mass of the compound will be reported as higher than the actual value. This is because the barometer is used to calculate the pressure of the gas, and the pressure is used to calculate the molar mass. If the pressure is too high, the molar mass will be too low.
A barometer is an instrument that is used to measure the pressure of a gas. The pressure of a gas is the force that the gas exerts on a surface. The pressure of a gas is usually expressed in units of atmospheres.The molar mass of a substance is the mass of one mole of the substance. The molar mass of a substance is usually expressed in grams per mole. Hence if the barometer reading is recorded to be higher than the actual value, the reported value of the molar mass of the compound will be too low.
