Answer:
9/5
Explanation:
First we took the variables at one side then just solves it....
The amount of grams of hydrogen that are in the water sample is;
3.985 g
<h3>Avogadro's number</h3>
We are given that;
Number of moles of oxygen in a sample of water = 12 × 10²³
- Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.
Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles
Now, molar mass of hydrogen is 1 g/mol and we know that;
Molar mass = Avogadro's number(6.023 × 10²³) moles
Thus;
6.023 × 10²³ moles = 1 g/mol
Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)
⇒ 3.985 g

Answer:
you sound like that guy on tik who yells and makes these angry faces because were sad and he makes our day better i forgot his user
Explanation:
you are very inspirational i hope ill bust some tears at your memes tho
Answer:
Hours Wages = $7.5 / Hour
Since we do not know the tips , let us assume it is x
Carmen Worked 24 hours
Total amount she earned = (24*7.5) + x = 250
180 + x = 250
x = 250-180 = 70
Carmen should earn tips more than $ 70 in 24 hours in order her to receive more than $250 in that week
