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 average speed is 160 meters a minute.
Answer: Liquid has no definite shape but it has definite volume. The particles are free to move over each other but are still attracted to each other. Liquids can be compressed into gas.
Hope this helps :)
The independent variable is the one factor you manipulate or change in the experiment.
The dependent is what you are measuring. The independent is the one thing you are altering so you can carry out your experiment.
