What else can I help you with?
A student carefully diluted 25.0 ml 0.6 M NaOH solution in 475 ml of distilled water What is the molarity of the diluted solution of base?
Assuming that the 25.0 ml are added to the 475 ml of water, not diluted to that volume:Moles of NaOH in the original 25 ml = 25/1000 x 0.6 = 0.015 moles Final volume = 25 + 475 ml = 500 ml. We have 0.015 moles in 500 ml, so 0.03 moles in a litre, Molarity = 0.03.

What volumes of 0.200 m hcooh and 2.00 m naoh would make 500 ml of a buffer with the same pH as of one made from 475 ml of 0.200 m benzoic acid and 25 ml of 2.00 m naoh?
In general buffer the Henderson/Hasselbach equation is valid to use:pH = pKa -log [(Ca)/(Cb)]In which:* Ca = concentration of weak acid (benz. or formic.acid) and* Cb = conc'n of their respective conjugated bases (benzoate and formiate)From tables it is found: pKbenz.acid = 4.20 and pKformic.acid = 3.80pHbenz.acid,sol'n = 4.20 - log[(475*0.200-25*2.00)/(25*2.00)] == equal pH values == pHformic.acid sol'n = 3.80 - log[(Va*0.200-Vb*2.00)]/(Vb*2.00)]in which Va + Vb = 500 mL of the (new) HCOOH/HCOO- buffer* Va = volume of the formic acid sol'n (HCOOH, in mL) and* Vb = volume of the (2.00M) NaOH sol'n.The rest is calculation. Outcome:equal pH values: pH = 4.246- log [(Va*0.200-Vb*2.00)]/(Vb*2.00)] = 4.246 - 3.80 = 0.446[(Va*0.200-Vb*2.00)]/(Vb*2.00)] = 0.358Va*0.200/Vb*2.00 - 1 = 0.3580.100*Va/Vb = 1.358Va = 13.58*Vb and with Va + Vb = 500 it comes to:Va= 465.5 mL and Vb = 34.5 mL
How to prepare 0.5M sulfuric acid?
To prepare 0.5M sulfuric acid, you would mix concentrated sulfuric acid with water in the correct ratio. For example, to make 500 mL of 0.5M sulfuric acid, you could mix 25 mL of concentrated sulfuric acid with 475 mL of water. Always remember to add acid to water slowly to avoid splashing and heat generation.
How many tones in coal?
Coal typically contains three primary types of coal: lignite, bituminous, and anthracite. These represent different stages of coal formation, with lignite being the youngest and softest, while anthracite is the oldest and hardest. Each type has a different carbon content and energy value.
