A diploid somatic ("body") cell has 2n = 20 chromosomes. At the end of mitosis, each daughter cell would have ______ chromosomes

kozerog [31]

Answer:

At the end of mitosis, 2n = 20

At the end of meiosis I, n = 10

At the end of meiosis II, n = 10

Explanation:

Mitosis is a type of cell division in which daughter cell produced are genetically identical to their mother cell. So, no. of chromosome does not change after mitosis.

So, at the end of mitosis, each daughter cell would have 20 chromosome.

Meiosis is a type of cell division in which mother cell produces two haploid cells ones with a single set of chromosomes.

Meiosis is a two step cell division, Meiosis I and Meiosis II.

In meiosis I, homologous pair separates, so no. of chromosomes becomes half.

In meiosis II, sister chromatids separates. So, the number of chromosomes remains same (i.e. Have same no. of chromosome as present in cell produced after meiosis I).

So, at the end of mitosis, each daughter cell would have 20 chromosome.

At the end of meiosis I, each daughter cell would have n = 10 chromosomes. At the end of meiosis II, each daughter cell would have n = 10 chromosomes.

You have a 0.8 L of a 0.5 M HCl solution. How many moles of HCl does this solution contain?

lions [1.4K]

Answer:

$\boxed {\boxed {\sf 0.4 \ mol \ HCl}}$

Explanation:

Molarity is concentration measured in moles per liters. It is the number of moles of solute per liters of solution. The formula is:

$molarity= \frac{moles \ of \ solute}{liters \ of \ solution}}$

We know the solution of HCl has a molarity of 0.5 molar and there are 0.8 liters of solution.

1 molar (M) is equal to 1 mole per liter.
Let's convert the molarity of 0.5 M HCl to 0.5 mol HCl per liter. This will make unit cancellation easier.

The moles of solute or HCl are unknown, so we can use x. Now, we can substitute all known values into the formula.

$0.5 \ mol \ HCl /L = \frac {x}{0.8 \ L}$

Since we are solving for the moles of solute (x), we must isolate the variable. It is being divided by 0.8 liters. The inverse of division is multiplication, so we multiply both sides by 0.8 L.

$0.8 \ L *0.5 \ mol \ HCl /L = \frac {x}{0.8 \ L} *0.8 \ L$

$0.8 \ L *0.5 \ mol \ HCl /L=x$

The units of liters (L) cancel.

$0.8 * 0.5 \ mol \ HCl= x$

$0.4 \ mol \ HCl=x$

This solution contains 0.4 moles of HCl.
