Find the mass, in grams, of 3.758 mol CH4. ( show work )

Chemistry
1 answer:
vladimir2022 [97]3 years ago
5 0

Answer:

The mass of CH4 is 60, 29 grams.

Explanation:

We use the weight of the atoms C and H for calculate the molar mass:

Weight of CH4= weight C+ 4 x weight H= 12,01 g/mol +4 x 1,008g/mol=

Weight of CH4 =16, 042 g/mol

1molCH4-----16, 042grams

3,758 mol CH4--X= (3,758 mol CH4 x 16, 042 grams)/1 mol CH4=60,285836 grams

Determine the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution?
UkoKoshka [18]

Taking into account the definition of molarity,  the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 \frac{moles}{liters}.

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity=\frac{number of moles}{volume}

Molarity is expressed in units \frac{moles}{liters}.

<h3>This case</h3>

In this case, you have:

  • number of moles= 30 moles
  • volume= 0.80 L

Replacing in the definition of molarity:

Molarity=\frac{30 moles }{0.80 L}

Solving:

<u><em>Molarity= 37.5 </em></u>\frac{moles}{liters}<em />

Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 \frac{moles}{liters}.
