How many grams of CO2 are in 2.1 mol of the compound?a. 21.0 g
b. 44.0 g
c. 66.0 g
d. 92.4 g
Answers
1 mole ------- 44.0 g
2.1 mole ----- > ?
g = 44.0 * 2.1 / 1
g = 92.4 / 1
= 92.4 g
answer d
hope this helps!

Mass is the quantity of matter present in a substance. The masses of the most abundant molecule of are 85.9325, 87.9296, and 89.9267 amu.
What are isotopes?
Isotopes are the elements of the same species with the same atomic number but differ in atomic mass and physical properties.
% abundance and mass of chlorine are:
Cl-35 = 34.9688 amu
Cl-37 = 36.9659 amu
% abundance and mass of oxygen are:
O-16 = 15.9949 amu
O-17 = 16.9991 amu
O-18 = 17.9991 amu
O -16 is the most abundant form of the oxygen isotope and Cl -35 of chlorine.
The masses of the most abundant molecule are given as:
Cl-35, Cl-35, O-16:
Cl-35, Cl-37, O-16:
Cl-37, Cl-37, O-16:
Therefore, 85.9325, 87.9296, and 89.9267 amu are the masses of the most abundant form of the molecule.

Chlorine has the following % abundance and mass:
Cl-35 = 75.76 %, 34.9688 amu
Cl-37 = 24.24 %, 36.9659 amu
Oxygen has the following % abundance and mass:
O-16 = 99.757 %, 15.9949 amu
O-17 = 0.038 %, 16.9991 amu
O-18 = 0.205 %, 17.9991 amu
Based in the % abundance O-16 is the most abundant oxygen isotope and Cl-35 is the most abundant chlorine isotope
So the most abundant molecule of Cl2O and their respective mass are as follows:
1) Cl-35, Cl-35, O-16
Mass = 34.9688 amu + 34.9688 amu + 15.9949 amu = 85.9325 amu
2) Cl-35, Cl-37, O-16
Mass = 34.9688 amu + 36.9659 amu + 15.9949 amu = 87.9296 amu
3) Cl-37, Cl-37, O-16
Mass = 36.9659 amu + 36.9659 amu + 15.9949 amu = 89.9267 amu

Answers
Answer:
The correct answer is option b, that is, when the Sun, Earth, and the moon are nearly in a line.
Explanation:
The low and high tides are caused by the moon. The gravitational force of the moon produces something known as the tidal force. This force makes the Earth and its water to bulge out on the side nearest to the moon and the side far away from the moon. These bulges of water are considered as high tides.
Similarly to the moon, the Sun also causes tides, but, they are smaller in comparison. However, when the Earth, moon, and the Sun line up, that is, which takes place during the new moon or the full moon, the solar and lunar tides reinforce each other, resulting in more extreme tides, known as spring tides. The spring tides are considered as the highest tides.

Answers
The answer is: D. Biological precipitation.
Biological precipitation is the deposition of minerals from solution by the agency of organisms.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass.
Ocean sediments originate from numerous sources:
1) biological activity (biogenous).
2) weathering and erosion of the continents (terrigenous/lithogenous).
3) volcanic eruptions (volcanogenous).
4) chemical processes (hydrogenous).
