What is the percent by mass of oxygen in carbon dioxide (CO2)?

Answers

72.7% is the percent by mass of oxygen in carbon dioxide. A percent is obtained by multiplying the result by 100.

One approach to show the concentration for an element within a compound or component in a combination is as a mass percentage. The mass percentage is computed by dividing the total weight of the combination by the mass of each component and multiplying the result by 100%. The mass percent is calculated by dividing the mass that contains the compound and solute by the mass for the element or solute.

Molar mass of oxygen = 32 g/mole

Molar mass of carbon dioxide = 44 g/mole

mass percentage of oxygen =(molar mass of oxygen/molar mass of carbon dioxide)× 100

=(32/44)× 100

=72.7%

To know more about mass percentage, here:

Answer : The percent by mass of oxygen in carbon dioxide is, 72.72%

Solution : Given,

Molar mass of oxygen = 16 g/mole

Molar mass of carbon dioxide = 44 g/mole

As we know that there are 2 atoms of oxygen and 1 atom of carbon present in the carbon dioxide.

So, the molar mass of oxygen, $O_2$ = 2 × 16 = 32 g/mole

Now we have to calculate the percent by mass of oxygen in carbon dioxide.

$\%\text{ by mass of oxygen}=\frac{\text{Molar mass of oxygen}}{\text{Molar mass of }CO_2}* 100$

Now put all the given values in this expression, we get

$\%\text{ by mass of oxygen}=(32g/mole)/(44g/mole)* 100=72.72\%$

Therefore, the percent by mass of oxygen in carbon dioxide is, 72.72%

Compared to a 0.1 M aqueous solution of NaCl, a 0.8 M aqueous solution of NaCl has a(1) higher boiling point and a higher freezing point
(2) higher boiling point and a lower freezing point
(3) lower boiling point and a higher freezing point
(4) lower boiling point and a lower freezing point

Answers

The correct answer is option 2. A 0.8 M aqueous solution of NaCl has a higher boiling point and a lower freezing point than a 0.1 M aqueous solution of NaCl. This is explained by the colligative properties of solutions. For the two properties mentioned, the equation for the calculation of the depression and the elevation is expressed as: ΔT = -Km and ΔT = Km, respectively. As we can see, concentration and the change in the property has a direct relationship.

Answer:

(2) higher boiling point and a lower freezing point

How does bias in the data affect experimental results?A. Bias makes the data harder to analyze.
B. Bias makes the results less reliable.
C. Bias makes the results easier to interpret.
D. Bias makes the results not publishable.

Answers

Answer:

Explanation:

Bias may make one side look worse than they actually are.

If you have bias data result, then you can’t trust on your outcome to be 100% accurate. So, your answer is B.

Hope this helps :)
