A certain alloy is a mixture of equal number A atoms and B atoms. B atoms are twice as heavy as A atoms. What weight of A atoms is needed to make 600 pounds of the alloy?
Homework Answers
Given that number of atoms are equal, So
Na = Nb
Also, B atoms are twice as heavy as A atoms
Wb = 2*Wa
Total weight of alloy = 600 Pound
Wa + Wb = 600 pounds
Since Wb = 2*Wa, So
Wa + 2*Wa = 600
3*Wa = 600
Wa = Weight of A atoms = 200 pounds

In small atoms, the number of neutrons and protons in the nucleus tend to be equal. As you move to the larger atoms, you tend to see more neutrons than protons. This is because more neutrons means more strong nuclear force without adding electrostatic forces the neutrons are needed to increase the gravitational interactions in the nucleus the neutrons are necessary for repelling the electrons from the nucleus

In order to determine the density of a certain metal alloy in a laboratory class a student is measuring the mass and the dimensions of a cylinder made out of this alloy. She finds the mass to be 111.0 g with an uncertainty of 0.5 g. She then measures the diameter and the height of the cylinder. The diameter is 59.0 mm, and the height is 17.0 mm. The student made these length measurements with a millimeter ruler. What is...
