A carbon-12 atom has a mass of 12.00000 amu. The mass of a proton is 1.00728 amu, and the mass of a neutron is 1.00866 amu. How
9966 [12]
<span>A carbon - 12 atom and a regular carbon atom would have the same number of protons which is 6. So a carbon - 12 atom would have 6 protons. Both, however, would differ in the number of neutrons. Carbon - 12 atom has 6 neutrons. To determine the mass defect of a carbon - 12 atom, we have to add the total mass of protons and the total mass of neutrons and subtract the known mass of a carbon - 12 atom. That would be like this.<span>
6 (1.00728 amu) + 6 (1.00866 amu) = x
<span>6.04368 amu<span> + 6.05196 amu = x</span></span>
12.09564 amu = x

Then subtract it with 12 amu to get the defect mass

12.09564 amu - 12.00000 amu = y
0.09564 amu = y

<span>So the defect mass would be 0.09564 amu.</span></span></span>

When equal molar amounts of the following sets of compounds are mixed in water, which will not form a buffer solution?
krok68 [10]

Nitric acid is a strong acid while the nitrate ion is a very weak base. Nitric acid is able to consume hydroxide ions. However, the nitrate ions present are unable to consume hydronium ions. As a result, the set of compounds does not form a buffer solution.

<h3></h3><h3>What Is Molar Mass?</h3>

A mole is the number of entities present in a substance, such as atoms, molecules, or ions. A mole of any substance is defined as 6.0221023 molecules. Just as we use a standard value to quantify diverse things, such as 1 dozen = 12 items, we utilise the mole to quantitatively calculate the size of the tiniest creatures.

The number of atoms in 12g (0.012 kg) of 12C isotope is equal to the number of particles in 1 mole of the substance. One of the most crucial facts to remember is that the mole of a material always includes the same number of entities regardless of the substance.

An atom’s valence electrons determine how an atom interacts with other atoms. Explain why.
Ksenya-84 [330]
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Therefore, we group elements whose atoms have the same number of valence electrons together in the Periodic Table. ... This tendency is called the octet rule, because the bonded atoms share eight valence electrons.
