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 =
Most ocean life is found in coastal habitats. Coastal habitats have more light than the deep ocean resulting in a higher concentration of organisms. Plant species are especially abundant in coastal habitats.
Answer:
both boxes will weigh the same since they have the same volume of glass marbles inside. (lmk if u need a more detailed explanation)
Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.
Answer:
1 mole =56 g
18.5 moles =56×18.5
<h3>=1036 moles </h3>
