To make a 0.25 mol solution of sodium nitrite, measure out 8.25 grams of sodium nitrite (NaNO2) (sodium nitrite has a molar mass of 69.01 g/mol) and dissolve it in enough water to make a total volume of 1 liter. This will give you a 0.25 mol/L solution of sodium nitrite.
Oh, dude, 025 on a silver piece means it's 2.5% pure silver. So, like, if you were hoping for 100% pure silver, sorry to burst your bubble. But hey, at least you've got a little bit of shiny silver in there!
2005 Lincoln cents are .975 Zinc & .025 Copper
A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms. More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.
1.25 Solution Method: 1. Convert 2.5% to decimal: 2.5 / 100 = .025 2 Compute answer: 50 * .025 = 1.25
.025 meters
.025 percent Solution Method: 250 ppm = the ratio 250:1,000,000 = the fraction 250/1,000,000 = the decimal value 0.00025 = the percentage .025 (i.e. 0.00025 * 100)
025 is the same as 25 which is greater than 5
It is: .025 times 80 = 2
I assume you mean 5 and 025 (but I'll answer for.025 also). 5 milligrams is larger than 0.025mg. However 5mg is smaller than 025 milligrams.
.025 is thicker than .012

No. 025 cents is 25 cents.
95 is greater than 025
They are: .025, 0.25, 2.5 and 25
