Answer:
0.03682 mL of mercury
Explanation:
We know the density of the mercury which is 13.58 g/mL
density = mass / volume
volume = mass / density
Now we can calculate the volume of 0.5 g of mercury:
volume = 0.5 / 13.58 = 0.03682 mL of mercury
Nitrogen is the chemical element with the symbol N and atomic number 7. ... At standard temperature and pressure, a colourless and odorless atomic gas with the formula N. nitrogen forms about 78% of Earth's atmosphere.
Density = Mass / Volume
Mass = Density * Volume
Mass = 45 * 7 * 8 * 10
Mass = 25,200 grams
