NaoH HAVE 6.022(10)23 IN HALF DROP.
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
No, they are not. "0.5 mole of NaOH" means that you have half a mole of sodium hydroxide. "0.5M of NaOH" means that you have half a mole of sodium hydroxide for every liter of solution. "0.5M" is also commonly written as "0.5 mol/L" or "mol L-1".
The solution to "cut and unit" is "cutting in half." "Cut and unit" sounds like "cutting a unit."
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
You can draw less current, half the current gives half the amount of volt drop. Or use a thicker cable because doubling the cross-section area would also give half the volt drop.

There seems to be a misunderstanding, "miles" is not a unit of measurement for NaOH concentration. If you meant molarity instead of miles, you need the molarity of NaOH in order to calculate the moles of NaOH in the given volume which can be converted to miles using the molar mass of NaOH.
There is one hydrogen atom in one formula unit of NaOH.
Take half volume of 1.0 M NaOH and add another half volume of water. Or Take 20.0 gram NaOH , carefully dissolve this completely in ca. 0.9 L water and then fill up to 1.0 L end volume.
Half a unit.Half a unit.Half a unit.Half a unit.
If NaOH is diluted to half of its original concentration, this would mean that the molarity has also been halved. During titration, this would result in requiring twice the volume of the diluted NaOH solution to reach the endpoint compared to the original concentration.
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
Yes you have to drop the fuel tank to access the fuel gauge sending unit on top of the tank.
It is 1.5 times the unit price.
