Molarity, is the concentration of a solution expressed in terms of moles solute per liter of solution. What is the molarity of a

pishuonlain [190]

molarity of the CuSO₄ solution = 0.68 moles/L

Explanation:

The formula for molar concentration is:

molar concentration (molarity) = number of moles / solution volume (L)

number of moles = mass / molecular weight

number of moles of CuSO₄ = 12.304 / 159.6

number of moles of CuSO₄ = 0.07709 moles

molar concentration of the CuSO₄ solution = 0.07709 / 0.1127

molar concentration of the CuSO₄ solution = 0.68 moles/L

Make the following conversions. Show your calculations.

Natalija [7]

Answer:

1. 500 cm = 5 m

2. 1000 g = 1 kg

3. 455 L = 45, 500 cL

4. 0.865 m = 0.00865 m or 8.65 * 10^-3 n

5. 33.5 cm = 335 mm

6. 0.0198 m = 19800 micrometers

7. 57.65 cg = 5.765 * 10^8 nanograms

8. 1000 L = 1 kl

9. 99 degrees F = 37.222 degrees C

Explanation:

1. One meter = 100 centimeters

500 centimeters/ 100 centimeters = 5 meters

2. One kilogram = 1000 grams.

1000 grams/1000 grams = 1 kilogram

3. One Liter = 100 centiliters

455 liters * 100 centiliters = 45, 500 centiliters

4. One meter = 100 centimeters

0.865 centimeters/100 centimeters = 0.00865 meters

5. One centimeter = 10 millimeters

33.5 centimeters * 10 millimeters = 335 millimeters

6. One meter = 1.0 * 10^6 micrometers

0.0198 meters * 1 * 10^6 micrometers = 19800 micrometers.

7. One centigram = 1.0 * 10^7 nanograms

57.65 centigrams * 1 * 10^7 nanograms = 5.765 * 10^8 nanograms.

8. One kiloliter = 1000 L

1000 L/ 1000 L = 1 kiloliter

9. The formula for finding Celsius is 5/9(f - 32)

So 5/9(99 - 32) = x

5/9(67) = x

x = 335/9 or 37.222 degrees Celsius.

Which of the following are isoelectronic?

OleMash [197]

Answer:

The correct answer is option C.

Explanation:

Isoelectronic species are those atoms or ions which same number of electrons.But they differ in physical and chemical properties.

Atomic number of nitrogen atom is 7.

$[N]=1s^22s^22p^3$

$[N]^{3-}=1s^22s^22p^6$

Number electron in nitride ions = $N^{3-}=10$

Atomic number of oxygen atom is 8.

$[O]=1s^22s^22p^4$

$[O]^{2-}=1s^22s^22p^6$

Number electron in oxide ions = $O^{2-}=10$

$[Ne]=1s^22s^22p^6$

Number of electrons neon = $Ne=10$

Hence, $N^{3-} , O^{2-} \& Ne$ are isoelectronic.
