Answer:
95.2 g/mol
Explanation:
To calculate the molar mass of MgCl2
We have to separately see the molar masses of Magnesium and Chlorine
Molar mass of Magnesium: 24.305 g/mol
Molar mass of Chlorine: 35.453 g/mol
As there are two atoms of chlorine in the said molecule so the molar mass of chlorine will be multiplied by 2.
35.453*2 = 70.906 g/mol
So the total molar mass of the said molecule = Molar mass of Mg + Molar mass of two atoms of chlorine
= 24.305 + 70.906
=95.211 g/mol
Rounding off to .1
95.2 g/mol
Wave A has the shorter wavelength due too the fact that the shorter the wavelength the higher the frequency as they have an inverse relationship.
A substance that has a solubility of 12 grams/L of water would require 36/12 = 3 liters of water to dissolve 36 grams of the substance.
The given blanks can be filled with meteorology, atmosphere, biosphere, SI, and scientific notation.
In the field of meteorology, scientists measure the pressure, temperature, and humidity. Their measurements come from the characteristics of the atmosphere, and hydrosphere, and they look at how the weather influences the biosphere and the geosphere. The units of their measurements come from SI and the metric system. The numbers usually are not large, so scientific notation is not used.
Answer:
6.58 atm total
3.29 atm NO2
3.29 atm O2
Explanation:
Balanced equation:
O3 + NO → NO2 + O2
There are equal numbers of moles of both reactants, so neither is in excess and either could be considered the limiting reactant.
( 1.30 mol NO) x (1 mol NO2 / 1 mol NO) = 1.30 mol NO2
( 1.30 mol NO) x (1 mol O2 / 1 mol NO) = 1.30 mol O2
<em>Total pressure by using the formula;</em>
P = nRT / V
= ( 1.30 mol + 1.30 mol) x (0.08205746 L atm/K mol) x (401.0 K) / (13.0 L)
= 6.58 atm
<em>Partial pressure for NO2;</em>
(6.58 atm) x (1.30 mol NO2) / (1.30 mol + 1.30 mol)
= 3.29 atm NO2
<em>Partial pressure for O2</em>
6.58 atm total - 3.29 atm NO2
= 3.29 atm O2
