9.184 liters CH2O at STP
I think this is correct. Good luck
Answer:
A. your running speed 1.5 m/s
B. your mass 70 kg
C. your de Broglie wavelength
m
Explanation:
Hello there!
In this case, since the equation for the calculation of the Broglie wavelength is:

We can assume a running speed of about 1.5 m/s and a mass of 70 kg, so the resulting Broglie wavelength is:

Best regards!
Answer:
2 hydrogen and 1 oxygen atoms
Explanation:
Element name = <u>strontium</u>
Answer:
285g of fluorine
Explanation:
To solve this problem we need to find the mass of Freon in grams. Then, with its molar mass we can find moles of freon and, as 1 mole of Freon, CCl₂F₂, contains 2 moles of fluorine, we can find moles of fluorine and its mass:
<em>Mass Freon:</em>
<em>2.00lbs * (454g / 1lb) = </em>908g of Freon
<em>Moles freon -Molar mass: 120.91g/mol- and moles of fluorine:</em>
908g of Freon * (1mol / 120.91g) =
7.5 moles of freon * (2moles Fluorine / mole Freon): 15 moles of fluorine
<em>Mass fluorine -Atomic mass: 19g/mol-:</em>
15 moles F * (19g / mol) =
<h3>285g of fluorine</h3>
