The air is going to come out because of the low pressure.

As long as you're breathing, you'll be fine : /p. s. if you aren't breathing, you'll pass out. mark as brainliest.

Using dilution equationm1v1 =m2v2 ; where m1 and m1 are the intiial and final concentration, and v1 and v2 are the initial and final volume.5  × 5 m = 8 l  × m2m2 = 25/8 = 3.125 mtherefore; the resulting molarity is 3.125 m
