Slav-nsk [51]
From\ 2nd\ Newton\ Law\ resultuant\ force: \\\\\ F_R=m*a=5kg*3,6\frac{m}{s^2}=18N\\\\
F=32N\\\\
F_f- friction\ force\\\\
F_R=F-F_f\\\\
F_f=F-F_R=32N-18N=14N\\\\Friction\ force\ is\ equal\ to\ 14\ N.

Number of moles = molar concentration × volume

= 2.5 × 5

= 12.5 mol

Volume of concentrated solution = 12.5/17.2

= 0.727 l of 17.2 M of sulphuric acid to be diluted.
