If it takes 20 beryllium atoms to equal the mass of two krypton atoms,what is the relative mass of beryllium compared to krypton?
A)1/10
B)1/20
C)40 times
D)100 times
E)10 times

Question

Quizplus · Accepted Answer

The mass ratio of beryllium to krypton is found by dividing the total mass of beryllium atoms by the total mass of krypton atoms in the given scenario. Since 20 beryllium atoms equal the mass of 2 krypton atoms, the ratio is 20 beryllium atoms / 2 krypton atoms = 10 beryllium atoms per krypton atom, meaning beryllium has 1/10 the mass of krypton.
