Consider the point on the plot where 10.0 g of naoh have been added. what amount of naoh, in moles, has been added? 0.308 mol fecl3 initially present

The moles of NaOH are 0.25 moles.

Explanation:

To calculate the number of moles, we use the following formula:

Calculations for the moles of NaOH:

Given mass of NaOH = 10 g

Molar mass of NaOH = 40 g/mol

Putting values in above equation, we get:

Hence, the moles of NaOH are 0.25 moles.

catya your not at all which answer i've seen you do this on another question!

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
