Question

Q4. The mass of an element E found in 1.00 mole of each
of four different compounds is 38.0 g, 57.Og, 76.0 g
and 114 g respectively. What is the possible atomic
weight of E?
(1) 19.0
(2) 38
(3) 57
(4) 76​

Answer 1

Answer:

Explanation:

A possible atomic mass of Q has to be a factor of 38, 57, 76, and 114.

19.0 fits this description:

38 = 2(19)

57 = 3(19)

76 = 4(19)

114 = 6(19)
