moles soluto :
Masa molar H2SO4 =1* 2+ 32 + 16 *4 = 98.0 g/mol
1 mol H2SO4 --------------- 98.0 g/mol
moles H2SO4 --------------- 5 g
moles = 5* 1 / 98.0
moles = 5 / 98
moles = 0.0510 moles H2SO4
Masa en kilogramo de solución :
100 gr / 1000 => 0.1 Kg
entonces:
Molalidad = moles / masa Kg
Molalidad = 0.0510 / 0.1
=> 0.51 molal
