Dwarf planets have not cleared other objects out of their orbital paths
Silicon and Germanium. You can conclude it from its position in the periodic table. Silicon and Germanium are in the same group of the Carbon. That implies that all three have the same number of electrons in the outer orbital, which is responsible for the bonds.
93,000 in scientific notation is fairly simple, you're just breaking down the number a tad so you don't have to use a huge number!
BUT! In scientific notation 93,000 is 9.3x10^4 - written out that's nine point three times ten to the fourth power! (:
I hope all is well, and you pass! Good luck, rockstar! (: If you have any follow up questions, or even any comments - pm me or just let me know!
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 =
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 =
Molality is defined as number of moles of solute dissolved in 1000 g of solvent
So, molality of solution =
