Question

Calculate the mass of 10.044*10^25 molecules of Oxygen
Pls help me ASAP

Answer 1

Answer:

Hi, consider the answer given below

You need to appreciate the fact that 6.022 x 10^23 molecules of oxigen atom weighs 16g.

Therefore applying this to the calculation of this question we say that

6.022 x 10^23 molecules = 16g

therefore 10.044 x 10^25 molecules is equivalent to what mass

(10.044 x 10^25) x 16/(6.022 x 10^23)

= 2668.61g

Answer 2

Answer:

The mass of the $10.044 * 10^{25}$ molecules of Oxygen is 5337.2g

Explanation:

We know that the mass of $6.022 * 10^{23}$ molecules of Oxygen is 32g.

Now the mass of one molecule of Oxygen is $\frac{32}{6.022 * 10^{23} }$.

Mass of $10.044 * 10^{25}$ is $10.044 * 10^{25} * \frac{32}{6.022 * 10^{23} } = 5337.2g$
