A) is your best answer.

Relative Dating gives the 'relative dating', which allows one to find the difference of age between many different of fossils. However, radioactive dating is used to get a more exact measurement of a fossil, but it can only be used for certain types of fossils.

hope this helps

The answer is A, the first choice. Relative dating gives a "relative" age range of something, such as "older" and "younger", but radioactive can give more specific ranges such as "100 BC" or "1912".

How many grams of the compound in the figure above are required to make 1 liter of a 0.5 M solution? (Note: The atomic masses, i
Dafna1 [17]

Answer:

This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.

The answer is: 30grams

Explanation:

According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M

Molarity or Molar concentration is calculated using the formula:

M= n/V

Where; M= Molarity (M) = 0.5M

n= number of moles (mol)

V= Volume (V) = 1L

Hence, number of moles (n) = M × V

n = 0.5 × 1

n = 0.5 moles.

To calculate the mass in grams of CH3COOH, we say;

Number of moles (n) × molar mass (MM)

Since atomic mass for (C= 12, H= 1 and O=16)

Molar mass of CH3COOH:

= 12 + 1(3) + 12 + 16 + 16 + 1

Molar mass of CH3COOH = 60g/mol

Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol

Mass = 30grams.

Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.

irina1246 [14]

Answer:

46 chromosomes

Explanation:

In mitosis (I think it is this process) the 46 chromosomes in cell A replicate themselves, so there are 92 in total in cell B. Then the chromosomes are pulled apart and the cell splits into 2 daughter cells, leaving 46 chromosomes in each.
