Answer:
209.4831 g
Explanation:
number of moles × molar mass = mass of substance in g
12.3 × ( 14.0067 + 1.00484 × 3 ) = 209.4831 g
Compare them accordingly with the formula of E=hc/wavelength
Hello!
<span>We have the following statement data:
</span>
Data:
<span>As the percentage is the mole fraction multiplied by 100:
</span>
<span>The mole fraction will be the percentage divided by 100, thus:
</span><span>What is the partial pressure of oxygen in this mixture?
</span>
<span>To calculate the partial pressure of the oxygen gas, it is enough to use the formula that involves the pressures (total and partial) and the fraction in quantity of matter:

27.6 - 22.3 = 5.3; you simply subtract the old density from the new density.
The water from the lake must first evaporate from the liquid state to the gaseous state and then condense in the air to form vapors.
The water molecules absorb energy while evaporating and release it when condensing. Their motion gets faster when they are evaporating and slows back down upon condensation.
