On the off chance that one of the reactants is in overabundance yet you don't know which one it is, you have to compute the hypothetical item mass for the both reactants, with a similar item, and whichever has the lower yield is the one you use to precisely depict masses/sums for the condition, since you can't have more than the non-abundance reactant can create.

Why do ionic compounds conduct electricity when dissolved in water?
kirill [66]
Conductive when liquid - ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move. So ionic compounds do not conduct electricity when they are solid, but they do conduct electricity when they are dissolved in water or when they are melted.

How many g of nacl do need to make 1.00L of 2.5% w/v solution of nacl in water?
iren2701 [21]
2.5 % w/v ( that means we have 2.5 grams of solute in 100 mL <span>solution )

1.00 mL = 1000 mL therefore:

2.5 g ------------- 100 mL
?? --------------- 1000 mL

1000 x 2.5 / 100 => 25.0 g of NaCl</span>
