Q

Kako izračunamo masni delež elementa v spojini?

A

masni delež elementa = št. atomov el. krat relativna atomska masa el. x ulomljeno z relativno molek. maso spojine krat 100%.

Q

Kako izračunamo masno razmerje?

A

Izračunamo ga iz razmerja molskih mas
Molska masa ima enoto gram/mol
m(x) : m(y) : m(z) (nato delimo z najmanjšim št.)
