Atomic Mass

mass of h = 8 atoms of h/molecule * 1.00794 g/mol = 8.06352g/mol of h in c7h8

mass of c7h8 = 8 atoms of H/molecule * 1.00794 g/mol + 7 atoms/molecule of C * 12.0107 g/mol = 92.13842 g/mol

h / c7h8 = 8.06352 / 92.13842 = 0.08752

0.08752 = 8.752% = 9%

The atomic number represents the number of protons in an atom's nucleus, determining its chemical properties and element identity. Atomic mass is the total mass of an atom, which includes the sum of its protons, neutrons, and electrons.

IF it donates an electron -then atom gains positive charge and if it accepts an electron then it acquires negative charge.

the mass of an atom is dependent on protons and neutrons in the nucleus and electrons decide the charge of an atom

the overall atomic mass is 204.37, but for thallium 203 it is 203, and for thallium 205, it is 205.

Nucleon Number (total number of protons and neutrons)

The average atomic mass of an element is close to a whole number when the element has nearly equal amounts of its isotopes, with atomic masses that are close to whole numbers themselves. This occurs in elements with only one stable isotope or with stable isotopes that have similar abundances.

The mass of an element is determined by the total number of protons and neutrons in its nucleus. This mass is typically measured in atomic mass units (amu) and is an average of all the naturally occurring isotopes of that element.

In a religious context, mass typically refers to a formal ritual in Christianity, particularly in the Catholic Church, where believers gather to commemorate the Last Supper of Jesus Christ, receiving the Eucharist as a central part of the service. It is considered a sacred and important ritual for Catholics to participate in regularly as a form of worship and spiritual communion.

The atomic mass of sodium is approximately 23 g/mol.

The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)

The atomic mass of arsenic is approximately 74.92 atomic mass units.

The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the letter "A" in the chemical symbol notation, where A = number of protons + number of neutrons in the nucleus of the atom.

Mass is a measure of the amount of matter in an object. It is a fundamental property of an object that determines its resistance to acceleration when a force is applied. The standard unit of mass in the International System of Units (SI) is the kilogram (kg).

The characteristic of an element that represents the average mass of its isotopes is called the atomic mass. Atomic mass takes into account the abundance of each isotope of the element and is typically listed on the periodic table as a weighted average.

The atomic mass number of an element represents the total number of protons and neutrons in the nucleus. Since the number of protons in an element's nucleus defines its identity, carbon, with the atomic number 6, always has 6 protons in its nucleus. Therefore, the atomic mass number of carbon is made up of these 6 protons and varying numbers of neutrons.

Neon's atomic number is 10.

The SI (metric system standard is the kilogram (kg). It is equal to 1000 grams (about 2.2 lbs).

g (grams)

kg (kilograms) - 1000 grams

mT (metric tons) - 1000 kilograms

US-Americans still use the imperial system

lb (pounds) - 16 ounces avoirdupois

oz (ounces)

CaCO3 +2HCl ------------> CaCl2 + CO2 + H2O

number of moles of CO2 in .44 grams = .44/ 44 = .01

From equation it is clear that 1 mole of CO2 is produced from CaCO3 = 1 mole

.01 mole of CO2 is formed from CaCO3 = .01 mole

Weight of .01 mole of CaCO3 is = .01mole *100 g/mole = 1 gram

weight % of CaCO3 is = 1*100/ 1.25 = 80 % w/w

I've post my answer, so why don't you show that answer here with the question. It's fare. I must be informed about my answer weather it is right or wrong.

The atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights. It is approximately equal to the mass of a proton or neutron, and is defined as 1/12 the mass of a carbon-12 atom.

Hydrogen is an element. Its atomic number is one. It has one proton in the nucleus, and one electron in the first orbital. It has no neutrons.

Mass is a measure of the resistance of an object to changes in velocity, as described by Newton's Second Law, F=ma (weight is the force generated when the acceleration is due to gravity).

The reference standard for mass is the International Prototype Kilogram, so you could use a set of scales to compare your object to that. You could measure the extension of a spring with the object hanging from it, knowing how much a spring extends normally (Hooke's law).

If you found yourself somewhere without gravity, you could spin the object round on the end of a rope and measure the force it takes to keep it in a circle, or attach a rocket which provides a known amount of thrust.

As a cataclysmic alternative, you could fire antimatter at the object until it was entirely destroyed, and measure the energy released using E=mc2 to find the mass destroyed, which will be your object and an equivalent mass of antimatter.

Atomic mass refers to the total mass of an atom, including the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which determines its chemical properties and place on the periodic table.

The atomic mass of water (H2O) is calculated by adding the atomic masses of its constituent elements, which are hydrogen (H) and oxygen (O). The atomic mass of hydrogen is approximately 1, and the atomic mass of oxygen is approximately 16. Therefore, the atomic mass of water is approximately 18 (1 + 1 + 16).

According to the following website, the Sears Tower weighs 222,500 tons. http://archives.stupidquestion.net/sq21199.html

The atomic mass of Rhodium (Rh) is approximately 102.91 atomic mass units.
