What is the pOH of a 7.5 x 10^-2 M H+ solution?

1 answer:

3 0

Well to go from H+ to pOH, you have to convert H+ to pH first.

H+ = 7.5 x 10^-2

Formula to get pH = pH= -log(H+)
Plug H+ in: pH= -log(7.5x10^-2)

pH= 1.125

now to get pOH we convert pH to pOH

formula for pOH= pOH=14-pH
plug pH in: pOH= 14- 1.125

Answer: 12.875

Hope this helps :)

B. How many atoms are in 2.15 moles of water?

finlep [7]

Answer:

$1.29*10^{24} mol$

Explanation:

For this problem, you will have to convert moles to atoms. Use Avogadro's number.

$2.15 mol=\frac{6.022*10^{23} atoms}{1 mol}$

How many milliliters of a 0.250 MNaOHMNaOH solution are needed to completely react with 500. gg of glyceryl tripalmitoleate (tri

choli [55]

Answer:

$7.48X10^3~mL$

Explanation:

For this question we have:

-) A solution NaOH 0.25 M

-) 500 g of glyceryl tripalmitoleate (tripalmitolein)

We can start with the reaction between NaOH and tripalmitolein. NaOH is a base and tripalmitolein is a triglyceride, therefore we will have a saponification reaction. The products of this reaction are glycerol and (E)-hexadec-9-enoate.

Now, with the reaction in mind, we can calculate the moles of NaOH that we need if we use the molar ratio between NaOH and tripalmitolein (3:1) and the molar mass of tripalmitolein (801.3 g/mol). So:

$500~g~tripalmitolein\frac{1~mol~tripalmitolein}{801.3~g~tripalmitolein}\frac{3~mol~NaOH}{1~mol~tripalmitolein}=1.87~mol~NaOH$
