What is the net charge of the atom C-16?

How many moles of hydrogen are in 5 moles of water?

How many atoms of hydrogen are in 5 moles of water?

How many grams of hydrogen are in 5 moles of water?

I had a beginning chemistry class in high school over 60 years ago!

the net charge on any atom is zero. Only ions carry a net charge.

one mole is 6.02 * 10^23 atoms.
Each molecule of water (H2O) has two hydrogen atoms.

each mole of H2O has a mass of 2*1 + 16 = 18 grams.

To determine the net charge of an atom, you need to know the atomic number and the number of electrons. The atomic number of carbon (C) is 6, which means it normally has 6 protons and 6 electrons, making it electrically neutral. However, if the atom is C-16, it implies an isotope of carbon with a mass number of 16. Isotopes have the same number of protons but a different number of neutrons. Neutrons do not affect the charge of an atom, so the net charge would still be zero for C-16.

To calculate the number of moles of hydrogen in a compound like water (H2O), you can look at the chemical formula. In water, there are two hydrogen atoms for every molecule of H2O. Therefore, the ratio of moles of hydrogen to moles of water is 2:1. If you have 5 moles of water, that means there will be 5 moles of hydrogen.

To determine the number of atoms of hydrogen in 5 moles of water, you can use Avogadro's number, which states that 1 mole of any substance contains 6.022 × 10^23 particles (atoms, molecules, ions, etc.). In 1 mole of water, there are 2 moles of hydrogen atoms. So, in 5 moles of water, there would be 5 × 2 × 6.022 × 10^23 hydrogen atoms.

To find the mass of hydrogen in 5 moles of water, you need to know the molar mass of hydrogen and the molar mass of water. The molar mass of hydrogen (H) is approximately 1.0079 grams/mol, and the molar mass of water (H2O) is approximately 18.0153 grams/mol. Since the ratio of hydrogen to water is 2:1, this means 1 mole of water contains 2 moles of hydrogen. Therefore, in 5 moles of water (which contain 10 moles of hydrogen), the mass of hydrogen would be 10 × 1.0079 grams.
