dgar would see the four substances separate, starting with the substance on the top layer to the substance on the bottom layer of the beaker. A. Honey, water, olive oil, ethyl alcohol
Use the formula first step: Use the formula molarity= mole/liter change ml to l plug in data to get .1=mole/.25 or .1M*.25liter which =.025 moles then divide .025 moles by two because there are two OH in Sr(OH)2 then multiply that by 265.76 (the molar mass of water) .0125*265.76 which is 3.32grams this is your answer
An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons
