I'm pretty sure its the first one
Explanation:
Answer:
Molarity of the solution is 0.26 M and molality of the solution is 0.28 m
Explanation:
Molar mass of benzoic acid = 122.12 g/mol
So, 14. g of benzoic acid =
of benzoic acid = 0.11 mol of benzoic acid
We know, density is the ratio of mass to volume
So, mass of 425. mL of solvent = ![(425.\times 0.92)g=391 g](https://tex.z-dn.net/?f=%28425.%5Ctimes%200.92%29g%3D391%20g)
Molarity is defined as number of moles of solute dissolved in 1000 mL of solution
Here solute is benzoic acid and total volume of solution is 425. mL
So, molarity of solution = ![\frac{0.11}{425.}\times 1000M=0.26M](https://tex.z-dn.net/?f=%5Cfrac%7B0.11%7D%7B425.%7D%5Ctimes%201000M%3D0.26M)
Molality is defined as number of moles of solute dissolved in 1000 g of solvent
So, molality of solution = ![\frac{0.11}{391}\times 1000m=0.28m](https://tex.z-dn.net/?f=%5Cfrac%7B0.11%7D%7B391%7D%5Ctimes%201000m%3D0.28m)
C2H6O + 3 O2 = 2 CO2 + 3 H2O.
Answer:
Nuclear
Explanation:
The material most often used in nuclear power plants is the element uranium. Although uranium is found in rocks all over the world, nuclear power plants usually use a very rare type of uranium, U-235. Uranium is a non-renewable resource. ... Nuclear power plants do not pollute the air or emit greenhouse gases.
Answer:
hmm i would have to say either robert hooke or isaac newton
