6.02 x 10^23. A mole will never change.
100/150.158 is 0.666 moles
if you have 100 liters how many moles does that equal?
There would be 0.75 moles in 1 liter of solution. You have 100 mL which is in fact 0.1 liters. so you would have 0.1 of 0.75 moles. 0.1 x 0.75 = 0.075 moles.
The numbers of moles in 100 kg of sodium is 4 349,76.
100 times Avogadro's Number = 6.022 X 1025.

.0104 mol
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
100 moles of NaCl
There would be 0.75 moles in 1 liter of solution. You have 100 mL which is in fact 0.1 liters. so you would have 0.1 of 0.75 moles. 0.1 x 0.75 = 0.075 moles.
4.00
They would be 2.10
The atomic weight of magnesium is 24.31; therefore, the number of moles in 100 gm is 100/24.31 = 4.11, to the justified number of significant digits.
