The answer to this question would be the second option or B (The moon's orbit is closer to Earth.) because there are multiple different high tides that are caused by either the moon being unusually close to the Earth or the moon is at it's Quarterly or New Moon phases.

Hope that this helped you! :D

A sample of h2so4 contains 2.02 g of hydrogen, 32.07 g of sulfur, and 64.00 g of oxygen. how many grams of sulfur and grams of o

saul85 [17]

Answer : The mass of sulfur and oxygen are present in second sample is, 115.44 and 212.72 grams respectively.

Solution :

As we know that the component of elements are in fixed proportions in the compound.

First we have to calculate the total mass of first sample.

Total mass of first sample = 2.02 + 32.07 + 64 = 98.04 g

Now we have to calculate the % of hydrogen, sulfur and oxygen.

$\% \text{ of H}=\frac{\text{Mass of H}}{\text{Total mass of sample}}\times 100=\frac{2.02g}{98.04g}\times 100=2.06\%$

$\% \text{ of S}=\frac{\text{Mass of S}}{\text{Total mass of sample}}\times 100=\frac{32.07g}{98.04g}\times 100=32.71\%$

$\% \text{ of O}=\frac{\text{Mass of O}}{\text{Total mass of sample}}\times 100=\frac{64g}{98.04g}\times 100=65.27\%$

Now we have to calculate the total mass of second sample.

$\% \text{ of H}=\frac{\text{Mass of H}}{\text{Total mass of second sample}}\times 100\\\\2.06\%=\frac{7.27g}{\text{Total mass of second sample}}\times 100\\\\\text{Total mass of second sample}=352.91g$

Now we have to calculate the mass of sulfur and oxygen.

$\% \text{ of S}=\frac{\text{Mass of S}}{\text{Total mass of second sample}}\times 100\\\\\text{Mass of S}=32.71\times \frac{352.91}{100}=115.44g$

$\% \text{ of O}=\frac{\text{Mass of O}}{\text{Total mass of second sample}}\times 100\\\\\text{Mass of O}=65.27\times \frac{352.91}{100}=212.72g$

Therefore, the mass of sulfur and oxygen are present in second sample is, 115.44 and 212.72 grams respectively.
