4 0

Answer:

182.933~ \text{g mol}^{-1}

Explanation:

\text{Atomic mass of cobalt(Co)} = 58.933~u\\\\\text{Atomic mass of nitrogen(N)}= 14~u\\\\\text{Atomic mass of oxygen(O)}=16~u\\\\\text{Molar mass of}~ \text{Co}\left(\text{NO}_3} \right)_2 = 58.933 + 2(14 +16 \times 3)~ \text{g mol}^{-1}\\\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=(58.933 + 124)~ \text{g mol}^{-1}\\\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=182.94~ \text{g mol}^{-1}

mixas84 [53]

Answer:

The answer is: <em>"Rarefactions"</em>

Explanation:

In a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. Places where particles of a medium crowd closer together are called compressions, and places where the particles spread farther apart are called rarefactions.

A gas has a volume of 590 mL at a temperature of –55.0°C. What volume will the gas occupy at 30.0°C? Show your work.
Mashutka [201]
Step 1: Convert the temperatures to K
-55 + 273 = 218 K = T1
30 + 273 = 303 K = T2

Step 2: Use the formula V1/T1 = V2/T2
590/218 = V2/303
V2 = 303 * (590/218) = 820.02 mL is the new Volume

How many grams of glucose(C6H12O6) are produced by 10.0 grams of water(H2O)?
GaryK [48]

Answer:

16.7 g of glucose

Explanation:

Convert grams of H₂O to moles.  <em>0.555 mol</em>

We can use the chemical equation to determine the theoretical yield.  Based on the equation, for every 6 moles of H₂O, 1 mole of glucose is produced.  The ratio of glucose moles to H₂O moles is 1/6.  

Multiply the moles of H₂O by the ratio to find moles of glucose.  <em>0.0925 mol</em>

Convert moles of glucose to grams.  <em>16.7 g</em>
