1. The mass of the last screw Cayden adds is 3.855 g given that Cayden has several screws on a scale, and the scale reads, 80.955 g and Cayden adds one more screw, and the scale reads 84.81 g. This can be obtained by subtracting the initial mass of screws from the final mass of screws.

   What is the mass of the last screw Cayden adds?

   Here in the question it is given that,

   • Cayden has several screws on a scale

   • Initially the scale reads 80.955 g

   • Cayden adds one more screw, and the scale reads 84.81 g

    

   We have to find the mass of the last screw Cayden adds.

   Let the mass of the last screw be x.

   ⇒ 80.955 g + x = 84.81 g

   ⇒ 80.955 g + x – 80.955 g = 84.81 g – 80.955 g

   ⇒ x = 3.855 g

   Hence the mass of the last screw Cayden adds is 3.855 g given that Cayden has several screws on a scale, and the scale reads, 80.955 g and Cayden adds one more screw, and the scale reads 84.81 g.
