PLEASE PLEASE HELP!! A pipe drips at 155mL/day- convert this rate to gallons/day (1gal=3.785L)

1 mL = L

so $155$ mL =$155\times10^{-3}$ L

Now, $1$ gallon = $3.785$ L , or $1$ L= $\frac1{3.785}$ gallons

so $155\times10^{-3}$ L= $155\times10^{-3}\times \frac{1}{3.785}=40.95\times 10^{-3}$ gallons

and this is for each day, so just divide by 1 (day) to get the ratw gallons/day

i.e. $40.95\times 10^{-3}$ gal/day

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
