Physics as repost please answer and help

Silver plating:
A student attempts the process of silver plating to determine the mass of a silver atom.
a series of objects are measured, then electroplated for a measure period of time, while maintaining a steady current through a solution of silver nitrate in tap water. After allowing the object to dry they measure the new mass of the object
The student noted down the results and drew a line of best fit then wrote down the result for a a single silver atom.

The accepted mass for a silver atom is 1.80 X 10^-25.
The student got -1.9.
The students value was much higher than the accepted value.
Evaluate the experiment stating potential sources which may account for any differences int he values.

Im really stuck please help.

"tap water"
but more likely, what are the units for the accepted and the measured?

I dont know it doesnt say but those are the 2 values for a single silver atom if that helps you figure out the units.

No, I know the units, the point is you don't know the units.
Google "tap water". What is in tap water? What are the pipes made of? Are you in an alkaline water area? and if so, what is alkaline water? The point is, silver nitrate added to "tap water" is not just a solution of silver nitrate. pH is likely another concern.
It should have been added to distilled water.

1)
Tap water is water supplied to a tap. Its uses include drinking, washing, cooking, and the flushing of toilets.
2)
Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as "soil") out of steel, copper, plastic, and cast iron. The straight sections of plumbing systems are called "pipes" or "tubes".
3)couldnt find
4)The pH level is a number that measures how acidic or alkaline a substance is on a scale of 0 to 14. ... Alkaline water has a higher pH level than regular drinking water. Because of this, some advocates of alkaline water believe it can neutralize the acid in your body. Normal drinking water generally has a neutral pH of 7.
Is this the sorta stuff i should write?

nothing comes up useful when i write:why is the mass of a silver atom higher than expected

and im not sure what to write please help me more

Lead pipes. For many centuries, water pipes were made of lead, because of its ease of processing and durability. ... Most of the lead pipes that exist today are being removed and replaced with the more common material, copper or some type of plastic.

I dont know what to link or write to answer the question, i did your research task but am still confused

As physics - cylinder Friday, January 5, 2018 at 11:09am
So is all this what i should right? i dunt know which bit is relevant as so much stuff comes up and i dont know what to link and what is required of me to write, now that i have given it a go could you please help

  1. So what are the units of 1.80 X 10^-25?
    1.9? kg, g, slugs, what?
