calculate the relative atomic mass of calcium given that the number of moles in 0.4 moles and mass is 16 g

The relative atomic mass of Calcium : 40 g/mol

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass / the relative atomic mass(Ar) :

Calcium (Ca) :  

moles = 0.4

mass = 16 g

output?

explanation:

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
