Density formula

Mass and volume are related to density of the matter,. If mass remain same and volume comes down its density will be high. \p[icture quora.com.

Density

For some reason, my students find it pretty difficult to to plug numbers into a simple formula. Even when I wasn’t teaching science last year, the science teacher used to always ask me what h…

The density of gases have been listed below in alphabetical order in the units of both metric and imperial. The chemical formula as well as molar mass has also been listed. below the table is an image version for offline viewing Gas Chemical Formula Molar mass Density Density – – g/mol kg/m3 lb/ft3 Air – […]

They are related by the the density triangle. They are related by the the density triangle. d = m/V m = d×V V = m/d DENSITY Density is defined as mass per unit volume. d = m/V Example: A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density? Step 1: Calculate the volume V = lwh = 10.0 cm × 10.0 cm × 2.00 cm = 200 cm³ Step 2: Calculate the density d = m/V = (433 g)/(200 cm³) = 2.16 g/cm³ MASS d = m/V We can rearrange this to get the expression for the…

Possible answer:Identifying the Molecular Formula of a HydrocarbonThe molecular formula of a hydrocarbon can be determined from its percentage composition and vapour density using the following steps:Step 1: Calculate the empirical formula of the hydrocarbon based on the percentage of carbon (C) and hydrogen (H) atoms in its composition. Assume a 100 g sample to simplify the calculation.Given that the hydrocarbon contains 80% C, the mass of C in 100 g of the sample is:80 g C = (80/12) mol…
