If 25.0 ml of seawater has a mass of 25.895 g and contains 1.295 g of solute, what is the mass/mass percent concentration of sol
Romashka-Z-Leto [24]
The  %  mass/mass concentration  of   solute  in the  seawater  sample  is  calculated  as  below


% mass =  mass  of the  solute /mass of the solvent(sea water)  x100
mass  of  the  solute =1.295  g
mass  of the  solvent(sea   water_)  =  25.895 g

there  the % mass =  1.295/25.895  x100 =  5.001 %

O, li, c which electrons experience the greatest effective nuclear charge? express your answer as a chemical formula.
Nataly_w [17]
<span>The effective nuclear charge of an atom = total electrons - inner electrons For O, ENC = 8 - 2 = 6 For Li, ENC = 3 - 2 = 1 For C, ENC = 6 - 2 = 4 The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>
