consider a balloon that will expand without restriction until it pops. If the balloon can hold a maximum of 5.0 L gas before it pops, and you're filling the balloon at a mass flow rate of 3.0g/s of hydrogen gas, determine how long you can fill the balloon before it pops if the gas and the surrounding atmosphere is at 26 c take the outside pressure to be 0.97 atm

The boiling point of liquids is very high what does it indicate

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.
