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 one staple?


Sagot :

mass of 1 staple = 6.8 g/210 staples
mass of 1 staple  = 0.032380952 g
Hope that helps!!

Answer:

210/6.8 = 1/x

210x = 6.8

x = 0.03238 grams = 32.4 milligrams
