Question

the absolute mass of 1 molecule of a substance is 5.32*10 -23g. what is its molecular mass? what could this substance be?

Answer 1

molecular mass of sub. =  mass of 1 mole of its molecules.
so here, mass of 1 molecule is  5.32 *10∧-23
and so, mass of 1 mole of molecule is  6.022* 10∧23 (Avogadro constant)

∴ moleculer mass of sub is equal to the mass of it 6.022* 10∧23 molecules 

 so,mass of 1 molecules of subtance                     = 5.32* 10∧-23
      mass for 6.022 *10∧23 molecules of subtance = ?
                                                                          =5.32* 10∧-23 ×6.022* 10∧23 
                                                                          = 32 g
and the 32g moleculer mass is for O2
so, the sub is O2

Answer 2

Answer:

oxygen

Explanation:

5.32*10^-23*6.022*10^-23=32
