  • How do you convert 87. 98 mL to liters? - Socratic
    Divide thru by 10^3 1*mL = 1xx10^-3*L, the m specifies "milli"=10^-3 Thus 87 98*mL = 87 98*cancel(mL)xx10^-3*L*cancel(mL^-1) = ??L
  • How do I calculate the molarity of 7. 24 * 10^2 mL of solution . . .
    #7 24xx10^2*mL-=7 24xx10^2*cancel(mL)xx10^-3*L*cancel(mL^-1)=0 724*L# Such operations are known as #"dimensional analysis"#, and we did a little example in the problem; we wanted an answer with units of concentration and we got one It is certainly not straightforward and intuitive, but it does work (eventually!) At your level you simply have
  • A cylindical container 30cm in diameter holds approach . . . - Socratic
    oil level falls ~~1 4 cm Given: Cylinder "diameter" = 30 cm, holds 30 L of oil Use 1 L of oil How far does the oil level fall? V_("cylinder") = A_(base) * h = pi r^2 h r = d 2 = 30 2 = 15 cm V_("cylinder") = pi 15^2 h = 225 pi h " "cm^3 Convert liters to cm^3 1 cm^3 = 1 mL; " " 1 L = 1000 mL 30 L xx (1000 mL) (1 L) xx (1 cm^3) (1 mL) = 30,000" " cm^3 1 L xx (1000 mL) (1 L) xx (1 cm^3) (1 mL
  • What mass of carbon dioxide results from complete combustion of a
    What mass of carbon dioxide results from complete combustion of a #9 75*L# volume of benzene?
  • How do I prepare 1 L of 2 mol L phenylmagnesium bromide?
    Here are the theoretical calculations for 1 L of 2 mol L PhMgBr > PhBr + Mg → PhMgBr "2 mol PhMgBr" × "1 mol PhBr" "1 mol PhMgBr" × "157 01 g PhBr" "1 mol PhBr" × "1 mL PhBr" "1 491 g PhBr" = "200 mL PhBr" "2 mol PhMgBr" × "1 mol Mg" "1 mol PhMgBr" × "24 30 g Mg" "1 mol Mg" = "50 g Mg" 1 or 2 crystals of I₂ Enough dry THF to make 1 L Note: The I₂ acts as a catalyst for the reaction
  • How to find the dimension formula for inductance and also . . . - Socratic
    Dimensions of L, MT^(-2)L^2A^(-2) Dimensions of R, ML^2T^(-3)A^(-2) Firstly consider resistance It's defining equation is, Ohm's law, V = IR implies R = V I Now V has units of (electric field)*(distance) But electric field has units (force) (charge) Also, charge has dimensions of (current)(time) and force has dimensions (mass)(length) (time)^2 Thus, dimensions of V is, [V] = (LMLT^(-2
  • Imagine the 10. 0g of ice has an initial temperature of -5 . . . - Socratic
    Total Energy required is: 5727 315J Latent Heat of Fusion of Ice: 334J g (L) Formula: E=mL Specific Heat Capacity of Ice: 2 108J (g^oC) (c) Specific Heat Capacity of Water: 4 187J (g^oC) (c) Formula: E=mcT To calculate this, first we must find the energy required to raise the temperature of ice from -5^oC to it's melting point: E=mcT E=10g * 5^oC * 2 108J (g^oC) E=105 4J Now, we must find the
  • What is volume of ethanol in 750mL of 12% ethanol solution?
    Well what is 12% of 750*mL? And of course we do not even know what sort of percentage percentage by volume, percentage by mass? We assume the former We do not even know in what solvent you have dissolved the alcohol
  • Question #b7836 - Socratic
    The phenolphthalein alkalinity is "15 1 meq CaCO"_3" L"; the total alkalinity is "23 6 meq CaCO"_3" L" Alkalinity in water is caused by the presence of "HCO"_3^-, "CO"_3^(2-) and "OH"^- ions Phenolphthalein alkalinity is determined by titration to a phenolphthalein end point (pH 8 3) It indicates the total hydroxide and half the carbonate present Titration to a methyl orange end point (pH
  • A student observes that 36. 76 mL of 1. 013 M NaOH are . . . - Socratic
    A student observes that 36 76 mL of 1 013 M NaOH are required to neutralize a 12 23 mL aqueous solution of sulfuric acid What is the concentration of sulfuric acid in the initial sample? Chemistry Reactions in Solution Neutralization
