It is noted that at some conditions consists atmospheric pressure =1.0atm and temperature = 26.6°C a container is completely full then you just need to calculate the percent (by volume) of air that would be displaced when all of theN2 (l) get evaporated. it is given that Liquid nitrogen has a density of 0.807 g/mL
The density of mercury is 13.595 g cm -3 . What will be this value in SI units? Give the SI units and their symbols for the following physical quantities:
Normally the alkaline earth carbonates (MCO3; M = Mg^2+, Ca^+2, Sr^+2, Ba+2) are insoluble in water. Why would the method used in this experiment work for calculating the molar mass of the alkaline earth? How would the calculations have to be cha..
