  • What is the mass of 211mL of a liquid that has a density of . . . - Socratic
    Approx 190*g By definition, rho, is given by the quotient rho_"density"="mass" "volume", and thus has units of g*mL^-1-=g*cm^-3 And so we simply rearrange
  • Question #021e1 - Socratic
    36 neutrons One way we have of differentiating between various nuclides of the same element is by writing the name of the element followed by a hyphen and the mass number of the nuclide In your case, you would have zinc-66, a nuclide of zinc that has a mass number equal to 66 Now, an atom's mass number, A, tells you the number of protons, which is given by the atomic number, Z, and neutrons
  • Google Lens - Search What You See - Socratic
    Discover how Lens in the Google app can help you explore the world around you Use your phone's camera to search what you see in an entirely new way
  • Question #16ac1 + Example - Socratic
    The key to understanding this problem is realizing that the volume of each gas is directly proportional to the number of moles of each gas When the hydrocarbon undergoes combustion, all of the carbon appears as CO_2 in the products, so in this example we see that the number of carbon atoms in the hydrocarbon must be 2, because the volume of CO_2 is twice that of the original hydrocarbon
  • Question #06d1b - Socratic
    From the Law for conservation of momentum we have for an incompressible fluid of density rho moving with velocity v the rate of change of momentum in the direction of motion x of fluid - (dp) dx = rho u (du) (dx) Rewriting it as (dp) dx + rho u (du) (dx)=0 For a constant density (incompressible flow) we can take the multiplicant rho u inside the differential It becomes (dp) dx + (d(1 2 rho u
  • Question #60f08 - Socratic
    This is a fascinating question, and one that is still being actively considered I can give you a basic answer here and point to better sources The moon almost certainly formed as a result of an enormous impact with a Mars-sized body very early in the history of the solar system The date isn’t precisely known, but was about 100 million years after the Earth formed The impacting body
  • Question #c7924 - Socratic
    Explanation: Given point #-> (x,y)-> (-3,10)# Given gradient #" " (m) =-2# Thus #y=mx+c" "# becomes #" " y=-2x+c# '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color (blue
  • Question #bcbe2 - Socratic
    The molarity of this solution is 0 25 mol L The molar mass of sucrose C_12H_22O_11 is 342 grams: (12 xx 12 + 22 xx 1+11 xx 16)=342 If we divide the given mass (85 5 g) by this molar mass, we get the number of moles of sucrose used: 85 5g (342 (g "mol")) = 0 25 mol Now, to determine the concentration, we divide the number of moles of solute by the final volume of the solution Since the
  • Question #45c4b + Example - Socratic
    It is not the best form for good communication Other than the specific "rules" of grammar in any language, what is "right" for writing is very flexible In this example however, there are both too many long sentences, and one wrong word ('necessary' should be 'necessarily') There are a number of writing evaluation programs, courses (some free) and blogs by writers that can help you to write
  • Question #cfae5 - Socratic
    a=0, 4 we will use the scalar (dot) product for two vectors veca=a_1hati+a_2hatj+a_3hatk," "vecb=b_1hati+b_2hatj+b_3hatk veca*vecb=|veca||vecb|costheta----(1) theta
