question 74

Multiple Choice

Acetone (mw = 58.08, P Acetone (mw = 58.08, P =232 mmHg) and butanone (mw = 72.11, P =100 mmHg) have the indicated molar masses and vapor pressures. A container holds 1.00 kg of butanone. How much acetone must be added to the butanone to elevate the total vapor pressure over the mixture to 125 mmHg at 25°C? A) 5.313 kg B) 290 g C) 188 g D) More information needed E) None of the above =232 mmHg) and butanone (mw = 72.11, P Acetone (mw = 58.08, P =232 mmHg) and butanone (mw = 72.11, P =100 mmHg) have the indicated molar masses and vapor pressures.

Impedance

The total opposition (combining resistance and reactance) a circuit presents to alternating current.

Capacitance

The ability of a component or circuit to collect and store energy in the form of an electrical charge, measured in Farads.

D'Arsonval Shunt

A D'Arsonval shunt is a precision resistor used in conjunction with a D'Arsonval meter movement to allow the measurement of high currents by diverting some of the current away from the sensitive galvanometer coil.
