Weight
Everything else stays the same. Weight is determined by how much you are being pulled down by gravity
58.08 g/mol
Formula: C3H6O
Melting point: -139°F (-95°C)
Density: 784 kg/m³
19685 because 1 km in inches is 39370 approximately so you just have to cut it in half
It's because proteins are very small and hard to see.
49 neutrons in each nucleus.
<h3>Explanation</h3>
For each nucleus:
Mass number = Number of protons + Number of neutrons.
The atomic number of a nucleus is the same as its number of protons. The atomic number of the nucleus here is 31. There are 31 protons in each nucleus.
- Mass number = 80;
- Number of protons = Atomic number = 31;
- The number of neutrons is to be found.
Again,
Mass number = Number of protons + Number of neutrons.
80 = 31 + Number of neutrons.
Number of neutrons = 80 - 31 = 49.
