<span>523 grams First, calculate the molar mass of CH3OH Atomic weight of carbon = 12.0107 Atomic weight of hydrogen = 1.00794 Atomic weight of oxygen = 15.999 Molar mass of CH3OH = 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now determine how many moles you have by dividing the number of atoms by avogadro's number moles = 9.83 x 10^24 / 6.0221409 x 10^23 = 16.3231 Now multiply the number of moles by the molar mass 16.3231 * 32.04146 = 523.0159557 Since we only have 3 significant figures, round the result to 3 significant figures. 523.0159557 grams = 523 grams</span>

Mekhanik [1.2K]

Answer:

The correct option is: stable environment

Explanation:

According to the Darwin's theory, natural selection is the concept by which all the small useful variations of traits are preserved.

According to Darwin, there are three <u>necessary and sufficient conditions</u> for the occurrence of natural selection:

1. struggle for existence

2. variation

3. inheritance

These conditions are said to be necessary because if these conditions are not satisfied then natural selection does not occur.

These conditions are said to be sufficient because if these conditions are satisfied, then natural selection will most definitely occur.
