Molar mass is the sum of all of its elements' average atomic mass in grams. Such as:

NH4 would be calculated by adding nitrogen's aam (14.007) and hydrogen's aam multiplied by four (1.0079 x 4 = 4.0316). Therefore, ammonium's molar mass would be (14.007+4.0316) 18.039. Rounded to sig figs.

How do you calculate density from molecular weight?

Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.


What are the units for molar density and how are they calculated?

The units for molar density are moles per liter (mol/L). Molar density is calculated by dividing the number of moles of a substance by the volume in liters that the substance occupies.


What is the relationship between molar mass and density in a substance?

The relationship between molar mass and density in a substance is that as the molar mass of a substance increases, its density also tends to increase. This is because a higher molar mass means there are more particles packed into a given volume, leading to a higher density.


How can one determine the number of moles in a substance when given its volume?

To determine the number of moles in a substance when given its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). The molar volume is a constant value that depends on the substance being measured.


What is the relationship between the molar mass and density of a substance?

The relationship between the molar mass and density of a substance is that the molar mass affects the density of a substance. Generally, substances with higher molar masses tend to have higher densities. This is because the molar mass represents the mass of one mole of a substance, and denser substances have more mass packed into a given volume.

How do you find no of atoms if molar mass and density is given?

This is actually a chemistry question, but I found it in the math section... well anyways you use an equation with avogadro's number. P(density)=(((#atoms)(molar mass))/((avogadro's number)(volume))). You're solving for #atoms so rearrange the equation. You have density, molar mass, and avogadro's number. As for volume, assuming you know what element this is (which you should know from the molar mass even if it's not given), you should be able to compute volume from the unit cell measurements. If you do not know unit cells... I'm not sure.

Work out the number of atoms per cm cubed from density?

To find the number of atoms per cm^3 from density, you first need to know the atomic mass of the material. Calculate the molar volume (cm^3/mol) using the molar mass of the material. Then convert to cm^3/atom by dividing by Avogadro's number (6.022 x 10^23). Finally, divide the material's density by the molar volume to get the number of atoms per cm^3.


How do you calculate the molar volume of a substance?

To calculate the molar volume of a substance, you divide the volume of the substance by the number of moles present. This can be done using the formula: Molar Volume Volume / Number of Moles.


What information would you need in order to convert molarity to percent by volume?

To convert molarity to percent by volume, you would need to know the molar mass of the solute and the density of the solution. With these values, you can calculate the volume of the solute in a given volume of the solution to determine the percent by volume.


How do you you find moles when given the mass and volume?

To find moles when given mass and volume, you need to first calculate the number of moles using the formula: moles = mass (g) / molar mass (g/mol). Then you find the concentration using the formula: moles / volume (L).


How do you calculate formula of hydrocarbon given volume only?

Heh. Good luck with that. If some sadist made me do it, I'd ignore the hydrogens, figure out what the volume of a carbon atom was based on its van der Waals radius, subtract a bit since a carbon-carbon bond is shorter than the sum of the vdW radii of the carbons, and then divide the volume by that to get the number of carbons n. Number of hydrogens is then 2n + 2.


How can one determine the molar mass of a substance by considering its density, pressure, and temperature?

To determine the molar mass of a substance using density, pressure, and temperature, one can use the ideal gas law equation, PV nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. By rearranging the equation to solve for molar mass (M), M (mRT)/(PV), where m is the mass of the substance, one can calculate the molar mass by plugging in the given values for density, pressure, and temperature.
