102kg/hr * 1000g/hr * 1lb/453.6g * 24hr/day = 5404.0 lb/day
They are colourless solids (salts) that do not conduct electricity when solid, but conduct electricity in aqueous solution as the ions (that carry charge) are free to move.
They have a high melting point due to the strong electrostatic forces of attraction between oppositely charged ions

Answer:
The number of moles of nitrogen in the tank are 1,98.
Explanation:
We apply the ideal gas law, convert the temperature unit in Celsius to degrees Kelvin, solve for n (number of moles). The gas constant R is used with a value of 0.082 l atm / K mol:
0°C= 273 K ---> 19, 71°C= 273 + 19,71= 292, 71K
PV= nRT ---> n=PV/RT
n= 4,97 atm x 9,583 L/ 0.082 l atm / K mol x 292, 71K=<em> 1, 98 mol</em>
