solong [7]2 years ago
5 0

Answer:

1s2: correct.

6s3: incorrect because the subshell s can hold up to 2 electrons.

5f10: correct.

4d3: correct.

2d4: incorrect because the second energy level just has the s and p subshells.

3p10: incorrect because the p subshell can hold up to 6 electrons.

Explanation:

Hello there!

In this case, according to the attached file, which shows the correct orbitals and electrons, we can proceed as follows:

1s2: correct.

6s3: incorrect because the subshell s can hold up to 2 electrons.

5f10: correct.

4d3: correct.

2d4: incorrect because the second energy level just has the s and p subshells.

3p10: incorrect because the p subshell can hold up to 6 electrons.

Best regards!

What is the mass of 3.35 mol Hg(IO3)2? 1,700 g 1,840 g 1,960 g 2,110 g
vichka [17]

Answer:- 1840 g.

Solution:- We have been given with 3.35 moles of  and asked to calculate it's mass.

To convert the moles to grams we multiply the moles by the molar mass of the compound. Molar mass of the compound is the sum of atomic masses of all the atoms present in it.

molar mass of  = atomic mass of Hg + 2(atomic mass of I) + 6(atomic mass of O)

= 200.59+2(126.90)+6(16.00)

= 200.59+253.80+96.00

= 550.39 gram per mol

Let's multiply the given moles by the molar mass:

3.35mol(\frac{550.39g}{1mol})

= 1843.8 g

Since, there are three sig figs in the given moles of compound, we need to round the calculated my to three sig figs also. So, on rounding off to three sig figs the mass becomes 1840 g.
