Question

Conductivity of two electrolyte solution A and B each one having concentration 0.1 molar are 8.5 into 10 raise to power minus 2 and 4.1 into 10 raise to the power minus 4 ohm per centimetre respectively which of the two offers less resistance to flow of current

Answer 1

At stp (273 k and 100 kpa), 1.15 dm3 of a gas has a mass of 3.96 g. Determine the molar mass of the gas.

The density of a gas is measured at 1.853 g / L at 745.5 mmHg and 23.8 °C.
