Answer:
(a) 0.047 g (b) 0.0016 oz (c) 0.0001 lb
Explanation:
The given mass of the sodium in the slice = 47 mg
(a) Mass has to be calculated in grams
The conversion of mg to g is shown below as:
1 mg = 10⁻³ g
So,
<u>Mass of sodium = 47 × 10⁻³ g = 0.047 g</u>
(b) Mass has to be calculated in ounces
The conversion of ounces to g is shown below as:
453.6 g = 16 oz
Or,
1 g = 16 / 453.6 oz
So,
<u>Mass of sodium = (0.047 × 16) / 453.6 oz = 0.0016 oz</u>
(c) Mass has to be calculated in pounds
The conversion of pounds to g is shown below as:
1 lb = 453.6 g
Or,
1 g = 1/ 453.6 lb
So,
<u>Mass of sodium = (0.047 × 1) / 453.6 oz = 0.0001 lb</u>
Answer:
The atomic mass of the other isotope = 106.905 amu
Explanation:
Step 1: Data given
Atomic mass of silver = 107.868 amu
Ag109 isotope has an atomic mass of 108.905 amu = 48.16 %
Step 2: Calculate the abundance of the other isotope
100.0 % - 48.6 % = 51.84 %
107.868 = 0.4816*108.905 + 0.5184*X
55.419352 = 0.5184X
X = 106.905
The atomic mass of the other isotope = 106.905 amu
Answer:
aqueous gallium chloride i think
Explanation:
Dispersion forces are the only type of intermolecular force operating between non-polar molecules, for example, dispersion forces operate between hydrogen (H2) molecules, chlorine (Cl2) molecules, carbon dioxide (CO2) molecules, nitrogen tetroxide (N2O4) molecules and methane (CH4) molecules.

Answer:
1. Convert the mass of A to moles dividing in molar mass
2. Convert the moles of A to moles of D (2mol A = 3mol D)
3. Convert the moles of D to mass multiplying by its molar mass
Explanation:
As you can see in the equation, 2moles of A produce 3 moles of D, the equation is:
2mol A = 3mol D
But in the problem you are having the mass of A and you need the mass of D. That means you require to convert the mass of A to moles. With the moles of A you can find the moles of D and, as last, you need to convert the moles of A to mass.
To convert mass to moles or vice versa you must use <em>Molar Mass. </em>That means, the answer is:
<h3>
1. Convert the mass of A to moles dividing in molar mass</h3><h3>
2. Convert the moles of A to moles of D (2mol A = 3mol D
)</h3><h3>
3. Convert the moles of D to mass multiplying by its molar mass</h3><h3 />
