Answer:
936g/mol
Explanation:
To find the molar mass of a molecule, you find the sum of the molar masses of each atom in the molecule.
This compound has 40 carbon atoms, 60 Hydrogen atoms, 10 Nitrogen atoms, 12 Oxygen atoms, and 2 Sulphur atoms.
The molar mass of:
- Carbon is 12g/mol
- Hydrogen is 1g/mol
- Nitrogen is 14g/mol
- Oxygen is 16g/mol
- Sulphur is 32g/mol
![(12 \times 40) + (60 \times 1) + (14 \times 10) + (16 \times 12) + (32 \times 2) = 936](https://tex.z-dn.net/?f=%2812%20%5Ctimes%2040%29%20%2B%20%2860%20%5Ctimes%201%29%20%2B%20%2814%20%5Ctimes%2010%29%20%2B%20%2816%20%5Ctimes%2012%29%20%2B%20%2832%20%5Ctimes%202%29%20%3D%20936)

Answer:
The answer is
<h2>0.99 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
![density = \frac{mass}{volume}](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20)
</h3>
From the question
mass of liquid = 3.75 g
volume = 3.8 mL
Substitute the values into the above formula and solve for the density
The density is
![density = \frac{3.75}{3.8} \\ = 0.98684210...](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B3.75%7D%7B3.8%7D%20%20%5C%5C%20%20%3D%200.98684210...)
We have the final answer as
<h3>0.99 g/mL</h3>
Hope this helps you
I think it'd because of (4), the reactivity of gold atoms, or rather, it's unreactivity. Gold, unlike most metals, doesn't form an oxide layer when exposed to air (Which is why it's so valued in jewellery, the metal will never tarnish, only stay gold forever). This makes it weaker, and so it can be formed in to thinner sheets.
However, (3), the nature of bonds between gold atoms also allows for the metal to be flattened, as metallic bonds aren't amazingly strong, and allow for metals to bend. This is what makes pure metals so weak, and why we use alloys.
