Calcium is located in the second group (column) and the fourth period (row) of the periodic table. The number under the symbol for calcium, Ca, tells you the molar mass of the element. This is the number of grams in 1 mole of calcium. The mass of 1 mole of calcium is 40.078 grams.

## How many grams CA?

Multiply moles of Ca by the conversion factor (molar mass of calcium) 40.08 g Ca/ 1 mol Ca, which then allows the cancelation of moles, leaving grams of Ca. The total number of atoms in a substance can also be determined by using the relationship between grams, moles, and atoms.

## How do you find the number of moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

## Is Avogadro’s Number?

Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 1023. … The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any).

## How many moles is 11.5 g Na?

There are 0.5 moles present in 11.5 g of sodium.

## How do we find atomic mass?

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
