Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in ...
How to Calculate the Molar Mass Now it’s high time to get closer to science. If you’ve been assigned to calculate the molar mass of a certain compound, you can actually use the periodic table as well as the amount of the given compound. Let’s recall the fact that the molar mass ...
relative isotopic mass is referred to as the mass of an atom of an isotope with respect to the mass of 1/12 of the mass of an atom in c-12. the isotopic abundances are used to calculate the average atomic weight and isotopic weights. average isotopic mass the percentage of abundance ...
How to convert ounces to kilograms with a formula Units: Units are often very useful when it comes to measurements of different objects. A ounce is a unit that is used to label for weight while a kilogram is a unit that is used to label the mass of objects. Answer and Explanation: ...
● calculate the relative velocity of two objects moving along the same line using vector analysis ● conduct practical investigations, selecting from a range of technologies, to record and analyse the motion of objects in a variety of situations in one dimension in...

you're calculating relative amounts of reactants and products in a reaction. In the first case, you usually have to weigh the individual components of a compound and calculate the number of moles of each. In the second case, you can usually find the mole ratio by balancing the equation ...
An atom has a neutral charge, so the positive and negative charges are equal to each other. The atomic number is also the number of electrons. Step 3 Calculate the number of neutrons by taking the mass number and subtracting the number of protons found in the nucleus. The mass number is...
