Suppose a solution has a pOH of 5.3. What is the concentration of hydronium ion, H3O+, in the solution?
The concentration of hydronium ion, H3O+, in the solution with pOH of 5.3 is 1.99 × 10-⁹M.
HOW TO CALCULATE HYDROGEN CONCENTRATION:
The pOH of a solution is given as 5.3. The pH of this solution can be calculated as follows:pOH + pH =145.3 + pH = 14pH = 14 - 5.3 = 8.7pH = 8.7.The hydrogen ion concentration can be calculated by using the following expression:[H+] = 10-pH[H+] = 10-⁸.⁷[H+] = 1.99 × 10-⁹MTherefore, the concentration of hydronium ion, H3O+, in the solution with pOH of 5.3 is 1.99 × 10-⁹M.

What is the answer with the proper significant figures 7.6+2.401+0.68=
Answer:
10.7
Explanation:
The addition of 7.6 + 2.401 + 0.68 = is 10.681.
According to the addition of sig figs, you want your answer to have the same amount of places, after the decimal point, as the least sig-fig figure.
7.6
2.401
0.68
+
----------
10.681 - Draw a line straight down from the least sig-fig figure (7.6)
So the maximum figure after the decimal point is one. Since 8 is greater than 5, you have to round up from 10.6 to 10.7.

A rectangular block weighs 121g. The dimensions of the block are 9.1cm by 5.4cm by 2.3cm. From this data, what us the density of the block in g/mL? Will tge block float or sink in water and how do you know? Show all your work on a piece of paper.
The density of the rectangular block is 1.07 g/mL.
From the question, we have the mass of the rectangular block as 121g
The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm
So we have the volume of the block as; 9.1cm × 5.4cm × 2.3cm = 113 cm^3
Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL
Having said that, we must also remember that;
Density = Mass/volume
Density = 121g/113 mL
Density = 1.07 g/mL

Write the electron configuration of a -2 ion with 16 protons.
Answer:
1s^2 2s^2 2p^6 3s^2 3p^6
Explanation:
Number of electrons = Number of protons. Originally, sulfur has 16 protons, but the question asks states 2- ions. So S^(2-), or a total of 18 protons. Follow the rules, and make sure the exponents add up to 18. 2 + 2 + 6 + 2 + 6 = 18 electrons.
