In February of 2014. The United States may federalism debate that had been an issue since the 1790s.

Reconstruction failed by most other measures: Radical Republican legislation ultimately failed to protect former slaves from white persecution and failed to engender fundamental changes to the social fabric of the South. When President Rutherford B. federalism debate that had been an issue since the 1790s almost mediately . Hayes removed federal troops from the South in 1877, former Confederate officials and slave returned to With the support of a conservative Supreme Court, these newly empowered white southern politicians passed black codes, voter qualifications, and other anti-progressive legislation to reverse the rights that blacks had gained during Radical Reconstruction.

What is the mass of 0.9210 moles of sulfur dioxide gas (SO2)?
Paul [167]

Answer:

58.944 g

Explanation:

From the question given above, the following data were:

Mole of SO2 = 0.9210 mole

Mass of SO2 =?

Next, we shall determine the molar mass of SO2. This can be obtained by adding the molar mass of sulphur and oxygen together as illustrated below:

Molar mass of SO2 = 32 + (2 × 16)

= 32 + 32 = 64 g/mol

Finally, we shall determine the mass of 0.9210 mole of SO2 as follow:

Mole of SO2 = 0.9210 mole

Molar mass of SO2 = 64 g/mol

Mass of SO2 =?

Mole = mass /Molar mass

0.9210 = mass of SO2 / 64

Cross multiply

Mass of SO2 = 0.9210 × 64

Mass of SO2 = 58.944 g

Thus, the mass of SO2 is 58.944 g.

I have to show my work after I find the atomic weight of each element please help !!
wariber [46]

Explanation:

For all of the questions, do the following calculation

\frac{isotope \:  \times abundance}{100}  +  \frac{isotope \:  \times abundance}{100} ...

As an example, I'll do question 1

\frac{204 \times 1.480}{100}  +  \frac{206 \times 23.6}{100}  +  \frac{207 \times 22.6}{100}  +  \frac{208 \times 52.3}{100}  = 207.20
