Answer:

0.0250 g.

Explanation:

∵ no. of moles (n) = mass / molar mass.

<em>∴ mass of Vitamine C = (n)(molar mass)</em> = (0.000142 mol)(176.12 g/mol) = 0.02501 g = <em>0.0250 g. "three significant figures"</em>

Calculate the number of atoms in 2 mol of sulfur dioxide (SO2).

Alex17521 [72]

Two moles of SO2 means 1.204x10^24 molecules, since there are 3 atoms in one molecule, multiply 1.204 x10^24 by 3 and you get 3.612x10^24.

Which unit can be used to express the concentration of a solution?

exis [7]

Answer: (3) ppm

Explanation: Concentration is defined as the amount of solute dissolved in a known amount of the solvent or a solution.

Parts per million (ppm) is used to express the concentration when a very small quantity of solute is present in a large quantity of the solution. It is defined as the mass of solute present in one milion $(10^6)$ parts by mass of the solution.

$ppm=\frac{\text {mass of Solute}}{\text {Mass of solution}}\times 10^6$

L/s is used to express flow rate.

J/g is used to express energy per unit mass.

kPa is used to express pressure.
