Answer:
5.84 M
Explanation:
First you have to convert grams of Ca(OH)2 to moles,
since molar mass is 74.093 g/mol, we divide the amount you have by the molar mass: (86.5 g)/(74.093 g/mol)= 1.1675 moles of Ca(OH)2
Then, knowing molarity is (moles/ volume in liters), we have to convert 200 mL to liters, which is 0.200 L
Putting it together, molarity = (1.1675/0.200) M= 5.84 M
The correct answer is D
Explanation:
Wave frequency is mainly determined by the number of waves that pass through a specific point. In a diagram, this can be found by analyzing the number of crests (top of the wave) and the space between them. For example, wave B is the one with the lowest frequency because there is only one crest and this shows only one wave passing at a specific point. On the opposite, wave D is the one with the highest frequency because this shows multiple crests and this indicates the frequency is high or that many waves pass through a specific point in a short time.
They are two representatives of the sublevels/energy levels.
