Rapid population growth is never good. Typically this leads to higher demand for survival essentials such as food and living space in a species. The demands for food can drive prey extinct and backfire on the growing species. This can lead to mass death and possible extinction for a over populating species
Answer - without osmosis it won't go from a low concentration to another low concentration. In this case it's water going into a cell which has low concentrations which the osmosis will limit it keeps the cell from exploding ;).
We require the information related to atomic mass of the compound and the number of each element present in the compound.
Option A
<u>Explanation:</u>
Molar mass is the amount of any compound present in a given sample. So we can determine the molar mass of any compound by the ratio of atomic mass of the compound to the amount of compound or element present in the sample.
So it can be defined as the mass of the compound in a given sample with respect to the number of elements present in that sample. Thus, we require the information related to atomic mass of the compound and the number of each element present in the compound.
Answer:
N(Au) = 1,20 × 10²²
Explanation:
1) n(Au) = m ÷ M = 4.60 g ÷ 197 g/mol = 0,02 mol
2) N(Au) = n(Au) × N(a) = 0,02 × 6.02*10²³ = 1,20 × 10²²
