First, find the molar mass of C6H12O6 (180.156 g/mol)
Then, using avagadro's number (6.02*10^23), find the amount of molecules in the sample.
(2.3*10^-3g)/180.156 g/mol = 0.0000128 mol
(0.0000128 mol)(6.02*10^23)= 7.6856*10^18 molecules
<span>The orange and yellow spheres represents Protons and neutrons in this model of an atomic nucleus.Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus.</span>
I believe an ionic compound is formed when two ions form an ionic bond.
Ans: pH = 9
<u>Given:</u>
Concentration of H+ ions [H+] = 1.0*10⁻⁹ M
<u>To determine:</u>
The pH of the above solution
<u>Explanation:</u>
pH = -log[H+]
pH = -log(1.0*10⁻⁹) = 9
