## How do you find the mass of a nickel in a coin?

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. 6 X 2 H atom- 12X1. 0079=12.09 Therefore: 6.022*10^23 atoms Ni will have mass = 58.693g.

## What is the volume of nickel?

Measured properties of the nickel are diameter = 2.14 cm, thickness 0.2 cm, mass 5.1 grams. This gives a volume of 0.719 cm3 and a surface area of 8.54 cm 2. This gives a calculated density of 7.09 gm/cm3 compared to the density of 8.9 gm/cm3 for the pure element from the periodic table.

## How do you find the mass of one mole of nickel?

According to the periodic table, the atomic mass of nickel (Ni) is 58.69 amu, which means that the molar mass of nickel is 58.69 g/mol. Therefore, we can divide 10.0 g of Ni by the molar mass of Ni to find the number of moles present.

## How many grams of magnesium are in 1 mole?

Each atom has a different size and therefore a different mass. The relative masses of each element can be found on the periodic table. For example, one atom of magnesium weighs 24.31 amu (atomic mass units). However, one mole of magnesium weighs 24.31 g.

## How many atoms are in a mole of platinum?

FREE Expert Solution. We’re being asked to determine the number atoms of platinum present in a ring with a mass of 8.50 g. Avogadro’s number gives us the number of entities present in 1 mole: 6.022 × 1023 Pt atoms in 1 mole Pt.
