Answer:
0.5455
Explanation:
The moles of benzene in the process stream in 1 sec = 450 moles
The moles of toluene in the process stream in 1 sec = 375 moles
So, according to definition of mole fraction:
Applying values as:
<u>Mole fraction of benzene in the process stream = 0.5455</u>
Hello.
balance the equation first
<span>Cu + 2AgNO3 ----> [2Ag] + Cu(NO3)2
</span>
<span>Now set up the equation </span>
<span>350gCu*(1molCu/ 63.546g Cu) * (2molAg/1molCu) * (107.8682g Ag/1molAg)
</span>
<span>Cancel out 1molCu with 1molCu, and cancel out 2molAg with 1molAg (it still remains 2mol Ag) </span>
<span>You are left with </span>
<span>350gCu*(1/63.546g Cu)*(2Ag/1)* (107.8682g Ag/1)
</span>
<span>350gCu*1*2*107.8682= 75507.74g
</span>
<span>now divide 75507.74g by 63.546g
</span>
<span>you get [1188.2374972460896g Ag]
</span>
Have a nice day
Answer:
2s
Explanation:
Given parameters:
Acceleration of the truck = 15m/s²
change in Velocity = 30m/s
Unknown:
Time taken for the body to slow down = ?
Solution:
Acceleration is the rate of change of velocity ;
Acceleration = 
time = 
Now insert the parameters and solve;
time = 
= 2s
Molecular weight calculation:
24.305 + (15.9994 + 1.00794)*2
Molar mass of Mg(OH)2 = 58.31968 g/mol
