Answer:
Iodine (I)
Explanation:
The atomic mass of Arsenic (As) is 74.92 amu. Also, we know that Halogen Group consists of following elements.
Fluorine, Chlorine, Bromine, Iodine, Astatine and Tennessine
And in given four options only Chlorine and Iodine belongs to halogen family. And we know that the atomic mass of chlorine is 35.45 amu which is less than that of Arsenic, therefore Iodine with atomic mass of 126.90 amu is the correct answer.
342.14 g/mol
Molar mass of Al= 26.98
Molar mass of S=32.06
Molar mass of O=16.00
(26.98)2+(32.06+(16.00×4))3=342.14
Answer:
28
Explanation:
electron = atomic number - charge(if the charge is positive and addition if the charge is negative)
electron = 30 - 2
electron = 28
Density = mass/volume
We are given a mass (which I am assuming is in kilograms) and a volume. Divide to find density.
Density of Saturn = 5.69x10²⁶ kg / 8.01x10²³ m³
Density of Saturn = 710. kg/m³
The density of water is 1000 kg/m³, which is higher than the density of Saturn. Since Saturn has a lower density than water, theoretically, Saturn would float in a gigantic bathtub filled with water.
<h3>
Answer:</h3>
Density: 710. kg/m³
Float? Yes.
