Density Mass/Volume


Mass Density x Volume


Volume Mass/Density


Meters to cm 1m = 100cm


Meter to millimeters 1 m = 1000mm


m to cm x100


grams to kg grams divided by 1000


1000g = 1kg


1 liter = 1000mL


1000mL = 1 liter


1kg = 1000g


1cm = 10mm


1km = 1000m


Molarity = moles/liters


moles = grams/molar mass


molecules = moles x 6.022 x 10^23


moles to molecules multiply by 6.02 x 10^23


Average atomic mass (Mass)x(abundance) + (Mass)(abundance)


T= PV/nR


Mass of 50.2g of N2 1) Convert grams to moles
2) N = 14.01 x 2 = 28.02 g/mol
3) n = 50.2g/28.02 g/mol = 1.79moles
