But density is m/V, so flip the equation over to get: m/V = (MMP)/(RT) = density of the gas. To find this, remember the relationship between number of moles and mass. How do you find the density of a gas number? ![]() The formula D= M/V is used at STP with M being equal to the molar mass and V being molar volume of a gas (22.4 liter/mole). What is the formula for density of a gas?Ī. The number of moles equals the mass of the gas divided by the molecular mass. To incorporate mass, we can use the number of moles, or n. To find density, we have to solve the equation for volume, or V.V = nRT / P. Pump gas composition varies by octane, by region, and by season. As you can now guess, this wide range is a reflection of the wide ranging composition. What is the specific gravity of gasoline?Ībout 0.720 to 0.770 The specific gravity of pump gas will typically range from about 0.720 to 0.770. What is the density of gasoline at 20 degrees Celsius? Multiply the specific gravity by 1,000 to calculate the density of the substance in kilograms per cubic meter (kg/cubic meters) units. Knowing the specific weight, you can easily compute the weight of any amount (volume) of a substance. How do you find density from specific weight? The result is the pounds per cubic foot, i.e., density. … Gas at STPĭensity at STP (Highlight to reveal Answer)ĭivide the weight (in pounds) of the shipment by the total cubic feet. ![]() If the density of the gas is equal to, then FW= 4.00 g/mol, 22.4 L/mol, so the density = 0.179 g/L. Gases (at standard atmospheric pressure, i.e.
