A flat 103-turn current-carrying loop is immersed in a uniform magnetic field. The area of the loop is 5.47 cm2 and the angle between its magnetic dipole moment and the field is 41.9°. Find the strength of the magnetic field that causes a torque of 2.95 × 10-5 N·m to act on the loop when a current of 2.33 mA flows in it. T=?
The gaseous product of a reaction is collected in a 25.0-L container at 27 degrees C. The pressure in the container is 300.0 kPa and the gas has a mass of 96.0 g. How many moles of the gas are in the container.
