Yes, i expect to find an atom with 26 protons and mass number of 52, because if it has different number of neutrons it could be a type of isotope. As if there is different number of neutrons in an atom, they make an isotopes of that atom and if we add the number of neutrons and number of protons we will find the mass number of that atom.
The answer is C. sugar water. Sugar can dissolve in water completely and form the solution. While other three are all heterogeneous mixture.
I believe the answer is 1-Water :)
To go from molecules to moles divide by Avogadro's number [<span>6.02x10^23]</span>
Example:
1.50x10^23 divided by 6.02x10^23 = 0.249 moles rounded to three significant figures
If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear. Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear.
