If the magnet loses its superconducting properties, all of the liquid helium could suddenly turn to a gas. If an MRI machine contains 1950 L liquid He with a density of 0.125g/mL, how many liters of He gas would be formed at 25°C and 1 atm? Use the ideal gas law. Round your final answer to two significant figures. Show your work

In the reaction between a crushed antacid tablet and vinegar what gas is emitted

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
