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
Answer:
Explanation:
The kPa-kilopascal is the unit of pressure. It was named after Blaise Pascal, a mathematician and physicist.
The kPa is 1000Pa. Kilo stands for 1000. Now what is a pascal?
A pascal is the amount of force(Newton) exerted per unit area.
1Pa = 1Nm⁻²
At the standard atmospheric level, the pressure is 101.325 x 10³ Nm⁻² i.e the atmosphere exerts a pressure of 101.325 x 10³N in an area of a body.
This unit is used to calculate pressure. It can be converted to other units.
The objects speed and direction of motion or change of its position
Answer:
25.0g is the mass of sulfur
Explanation:
The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.
To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:
<em>Moles O = Moles S:</em>
12.5g O * (1mol / 16g) = 0.781 moles
<em>Mass S:</em>
0.781 moles * (32g / mol) =
<h3>25.0g is the mass of sulfur</h3>
