Calculate the molarity of 48.0 mL of 6.00 M H2SO4 diluted to 0.250 L

const2013 [10]

Answer:

The answer is 1.15m.

Since molality is defined as moles of solute divided by kg of solvent, we need to calculated the moles of H2SO4 and the mass of the solvent, which I presume is water.

We can find the number of H2SO4 moles by using its molarity

C=nV→nH2SO4=C⋅VH2SO4=6.00molesL⋅48.0⋅10−3L=0.288

Since water has a density of 1.00kgL, the mass of solvent is

m=ρ⋅Vwater=1.00kgL⋅0.250L=0.250 kg

Therefore, molality is

m=nmass.solvent=0.288moles0.250kg=1.15m

Lithium and fluorine undergo ionic bonding. Using the noble gas electron configurations for each (below), please explain the pro

Slav-nsk [51]

Answer:

Lithium loses one electron to fluorine and forms ionic bond, having formula $LiF$ .

Explanation:

Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is $[He]2s^1$ .

Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is $[He]2s^22p^5$ .

Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged. This is done in order that the octet of the atoms are complete. These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.

Thus, the formula of calcium chloride is $LiF$ .
