If you place one staple on an electronic balance,the balance still reads 0.0 grams.however,if you place 210 staples on the balance ,it reads 6.80 grams. What is the mass of on staple?

210/6.8 = 1/x

210x = 6.8

x = 0.03238 grams = 32.4 milligrams

To find the mass of one staple, we need to determine the difference in mass when we add 210 staples to the electronic balance.

Let's start by calculating the additional mass of the 210 staples. The difference in mass between the balance reading with 210 staples and the initial reading with one staple is 6.80 grams - 0.0 grams = 6.80 grams.

Now, we can calculate the mass of one staple by dividing the total additional mass (6.80 grams) by the number of staples (210).

Mass of one staple = Total additional mass / Number of staples
= 6.80 grams / 210 staples

To find the mass of one staple, we divide 6.80 grams by 210.

Mass of one staple = 0.03238 grams

Therefore, the mass of one staple is approximately 0.03238 grams.
