Answer:

4.56 X 10^ -4 g/mL

Explanation:

A solution is  prepared by diluting 6.0 mL of a 7.6 x 10-4 g/mL solution to a total volume of 10.0 mL. Calculate the concentration of the dilute solution.

(7.6 X10^-4  gm/m L) x( 6.0 m L ) = 45.6 X 10^-4 g

this is dissolved )in 10 m L=45.6 X 10^-4  g/ 10

4.56 X 10^ -4 g/mL

check

6/10 =0.6

4.56/7.6 = o.,6

An aluminum block has a mass of 82.0 g and a volume of 12.8 cm3. what is the block's density to the nearest g/cm3?
aksik [14]
Density is mass over volume. If you put it into a formula it would look like this:

D = \frac{m}{v}

Based on the problem given, you can see that the mass of the aluminum block is 82.0 g and the volume is 12.8 cm3. Just put that into your equation and solve for it:

D = \frac{m}{V}=  \frac{82.0g}{12.8cm^{3} }  = 6.4g/ cm^{3}

The answer is then letter C.

If a sample contains 70.0 % of the R enantiomer and 30.0 % of the S enantiomer, what is the enantiomeric excess of the mixture?
NeTakaya

Answer:

the enantiomeric excess of the mixture is 40%

Explanation:

The computation of the enantiomeric excess of the mixture is shown below:

As we know that

= |\frac{R - S}{R + S} |\times 100\\\\= |\frac{70 - 30}{70 + 30}| \times 100\\\\= 40\%

Hence, the enantiomeric excess of the mixture is 40%

Answer:

Option (3) southern states threatened to secede from the Union over the issue of slavery

Explanation:

By the 18th century, the United States faced a number of issues. For example, the slave trade was one of the issues that resulted in the state being brought into turmoil. This was because the United States was already divided into two - the Northern region and the Southern region. The Northern region was the one region that still held to slave trade despite it being abolished. The South, offered slaves freedom. Thus, the movement of he slaves from the North to the South was a major issue. Thus, the war was over the trade as the north though it was suffering due to the decrease in slave labor.
