When sodium chloride (NaCl) reacts with silver nitrate(AgNO3), silver chloride precipitates. Determine the mass of silver chloride is produced from 75.0 grams silver nitrate
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:
15.0 moles of gas are in a 5.00L tank at 22.2°C. compute the difference in pressure between CH4 and an ideal gas under these circumstances. The van der Waals constants for CH4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
Compute the number of moles - As we know many volatile substances are present in Earth's atmosphere in trace amounts.
