Answer:</h2>
We will use dimensional analysis to solve this.
We will need the molar mass of barium, which is 137.33 g/mol.
50g × 
= .36 mol Ba
There are <em>.36 moles of barium</em> in 50g of barium
I don’t know the answer to this question
Answer:
The isotopic mass of 41K is 40.9574 amu
Explanation:
Step 1: Data given
The isotopes are:
39K with an isotopic mass of 38.963707u and natural abundance of 93.2581%
40K with an isotopic mass of 39.963999u
41K wit natural abundance of 6.7302 %
Average atomic mass =39.098 amu
Step 2: Calculate natural abundance of 40 K
100 % - 93.2581 % - 6.7302 %
100 % = 0.0117 %
Step 3: Calculate isotopic mass of 41K
39.098 = 38.963707 * 0.932581 + 39.963999 * 0.000117 + X * 0.067302
39.098 = 36.33681 + 0.0046758 + X * 2.067302
X = 40.9574 amu
The isotopic mass of 41K is 40.9574 amu
Ionization refers to the process of losing or gaining electrons. The correct answer is D.
Answer:
A compound by definition contains at least 2 different kinds of atoms. A Hydrogen molecule contains only one kind of atom, 2 hydrogen atoms
