Squirrels, nature's speed bumps?
a percent solution is usually weight to weight but the density of water is 1 so weight and volume are the same (gm mL) 400gm in 1L of water 40% NaOH has a molecular weight of 40 g/mol 40% solution is 10M (10M x 40 g/mol x 1L 400 gm NaOH) be very careful - use safety glasses/gloves/coat the solution will get very hot so I would suggest using a PP container and not glass measure out about 60% of the total volume of water and add the NaOH slowly bring the volume up to the final volume you may notice that less/more water is needed to make the final volume - this may be due to water in the air or water in the NaOH this is okay and is captured in the percent and Molarity as this is the molecular component in a set volume hope this helps
Why windows? If you really want something like that try to check out android If not just browse through a windows phone selection. I have an iphone 5 and i enjoy it, and im not an apple fanboy noob
A favorite of mine is The Children's Place. It can be expensive if you just walk in to the store, but they have great sales online and a much bigger selection. Also, if you Google The Childrens Place Coupon Codes you can easily find codes to get you at least 15% off your entire order and it's always only $5 for shipping no matter how much you buy.
