What would be the molarity of a solution made from 86.5 g Ca(OH)2in 200.0 ml of water?

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

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
