How many representative particles are there in 0.15 moles of hydrochloric acid? * 0.903 x 10^23 formula units
9.03 x 10^22 formula units
0.903 x 10^24 formula units
9.03 x 10^24 molecule

Ithink the answer is c

Heating it up with cause a quicker reaction time

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
