Answer:
Leon
Explanation: all take up space and will have a mass to it.
Answer:
There are 0.1 moles of solute in 250 mL of 0.4 M solution
Explanation:
because it is
Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container. ... The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy
Hope this helps
First let us calculate for the number of moles needed:
moles NaOH = 0.125 M * 0.500 L = 0.0625 mol
The molar mass of NaOH is 40 g/mol, hence the mass is:
mass NaOH = 0.0625 mol * 40 g/mol
<span>mass NaOH = 2.5 grams</span>
