An 8.00 mass % aqueous solution of ammonia has a density of 0.9651g/ml. Calculate the molality, molarity, and mole fraction of NH3. This question seems simple but I cannot seem to remember how to do this. Help please?
An industrial chemist is studying smAll organic compounds for their potential use as an auto antifreeze. When 0.243g of a compound is dissolved in 25.0 ml of water, the freezing point is -0.201 degree celcius. (A) Calculate the molar mass of compound (dH2O= 1.00g/ml) at temp o...
Basically the arcsin is the same as sin^-1 so the sin^-1(.5)= 30 degrees You can use a unit circle or a 30-60-90 triangle to figure it out.
How do i solve this equation over the interval [0degrees,360) cot(theta)+2csc(theta)=5
math (taylor polynomials)
Find the degree 3 Taylor polynomial T3(x) of the function f(x)=(7x+50)4/3 at a=2 Find the second-degree Taylor polynomial for f(x)=4x2−7x+6 about x=0 thank you! (:
Math (linear approximation)
Find a linear approximation of the function f(x)=(1+x)^(1/4) at a=1, and use it to approximate the numbers (.95)^(1/4) and (1.1)^(1/4). Round your answers to the nearest thousandth Cheers in advance!
Compare the value you obtained from average bond energies: (260Kj) to the actual standard enthalpy of formation of gaseous benzene, 82.9 kj. What does the difference between these two values tell you about the stability of benzene?
You can plug in zero for x and solve for y. then plug in zero for y and solve for x to get your values for x and y. x=200 y=-100
1) A price p (in dollars) and demand x for a product are related by 2x^2+6xp+50p^2=10600. If the price is increasing at a rate of 4 dollars per month when the price is 30 dollars, find the rate of change of the demand. 2) a) The price (in dollars) p and the quantity demanded q...
