Calculate the mass of carbon dioxide present in 445 mL at 225 degrees celsius and 1.783 ATM?
the equation you need is PV=nRTP=1.783 atmV=445 mL (convert to L by multiplying by .001)n=moles(what you're looking for)R=.08206T=225 (change Celsius to Kelvin by adding 273)solve for n to get the amount of moles and then multiply the moles by the molar mass of CO2 to get the mass :)
How many moles of C6H10S are in 225 grams?
1.97
How many grams of NH4NO3 would be required to prepare 0.500 L of a solution that is 0.450 M in NH4NO3(aq)?
NH4NO3's molar mass = 80.0gMolarity = moles of solute / liters of solution0.450 M = X / 0.500 LX = .225 molesNow we must convert X to grams because it is currently in moles.(.225 moles) / 1 * ( 80.0 grams ) / 1 mole =18 grams of NH4NO3
How would you prepare dilute sulfuric acid from concentrated sulfuric acid for use in an experiment?
Add the acid to water. Do NOT add water to the acid as it will boil and split acid everywhere. Please say 100 mL of water in a beaker and slowly add sulphuric acid to it. To change the molarities of the acid you need to do come calculations. If you have say 50mL of 5M sulphurtic acid and you want to make it say 1M sulphuric acid. Then use the eq'n moles = [conc] X vol(mL) / 1000 So 5M x 50mL / 1000 = 1M x vol(mL)/1000 Algebraically rearrange/. vol(mL) = 5M x 50mL / 1M NB THe '1000' cancel down. vol(mL) = 250mL In this case have 175 mL of water in a beaker, slowly add the 50mL (H2SO4), to avoid spitting. You will then have 225 mL. So then slowly add a further 25 mL of water to make the concentration 1M. NB 225mL of sol'n will be of the wrong concentration, that is why you add a small final amount of water.
How many grams of zinc can react with 225ml of 0.200 m HCl solution?
Balanced equation first.Zn + 2HCl - ZnCl2 + H2now we find moles HCl by....Molarity = moles of solute/Liters of solution ( 225 ml = 0.225 Liters )0.200 M HCl = X moles/0.225 Liters= 0.045 moles HCl================Now, drive reaction backwards.0.045 moles HCl (1 mole Zn/2 mole HCl)(65.41 grams/1 mole Zn)= 1.47 grams zinc reacted----------------------------------

What is 225 pounds?
On Earth, a mass of 225kg weighs 2,205 Newtons or 496 lbs.
How many kilograms is 225 newtons?
You cannot convert from newtons to kilograms because the newton is a force unit and the kilogram is a mass unit. However, near the surface of the earth, a 22.9-kg mass would weigh 225 newtons.

How many cups is 225gram?
Impossible to say with out knowing 225-grams of what? There must be a link between Mass (225-g) and Volume (cups). Think of it this way...one cup of feathers weighs much less than one cup of rocks.
16 percent of 225?
16% of 225= 16% * 225= 0.16 * 225= 36
What is 225 percent of 100?
225. If 100% of 100 is 100, then 225% of 100 is 225.
What is 87.5 percent of 225?
87.5% of 225= 87.5% * 225= 0.875 * 225= 196.88
