`10^(22)` atoms of an element X are found to have a mass of 930 mg. Calculate the molar mass of the element 'X'.

Explanation

Mass of `10^(20)` atoms of the element X= 930 mg
Mass of `6.022xx 10^(23) (N_(A))` atoms of the element `X =((930 mg) xx (6.022 xx 10^(23)))/(10^(22)) = 56004 mg = 56 g`
` therefore ` Molar mass of the element = 56 g
