Liquid nitr ogen is obta ined from liquefi ed air and is used to prepare froze n goo ds an d in low-tem perat ure re sear ch. Th e den sity o f the liquid at its boilin g point (-196^circ C or 77 K) is 0.808g/cm^3 . Conve rt the dens ity to unit s of kg/m^3

To convert the density of liquid nitrogen from grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³), we need to use the conversion factor between these two units.<br /><br />1 g/cm³ is equal to 1000 kg/m³.<br /><br />Given that the density of liquid nitrogen at its boiling point is 0.808 g/cm³, we can convert it to kg/m³ as follows:<br /><br />0.808 g/cm³ × 1000 kg/m³/g = 808 kg/m³<br /><br />Therefore, the density of liquid nitrogen at its boiling point is 808 kg/m³.
