Answer:
One mole
Explanation:
It tells u the concentration
The Heisenberg uncertainty principle listed above states that it’s impossible to determine with high precision both the momentum and position of an electron simultaneously.
Answer:
6.64
Explanation:
so moles

then do =4.01×10^24/6.02×10^23
you get the answer as 6.6445 u only need to write the answer to
3.S.F 6.64 moles
hope this make sense :)
Answer:
The root mean square speed of O2 gas molecules is
<u>519.01 m/s</u>
<u></u>
Explanation:
The root mean square velocity :



Molar mass , M
For He = 4 g/mol
For O2 = 2 x 16 = 32 g/mol
O2 = 32/1000 = 0.032 Kg/mol
First calculate the temperature at which the K.E of He is 4310J/mol
K.E of He =


K.E of He = 4310 J/mol


<u>Now , Use Vrms to calculate the velocity of O2</u>
