Part C<br> Number of molecules in 8.437x10-2 mol C6H6
N76 [4]

Answer:

There are 5.08\times 10^{22}\ \text{molecules of}\ C_6H_6  

Explanation:

In this problem, we need to find the number of molecules in 8.437\times 10^{-2} mol of C_6H_6.

The molar mass of C_6H_6 is 6\times 12+1\times 6=78\ g/mol

No of moles = mass/molar mass

We can find mass from above formula.

m=n\times M\\\\m=8.437\times 10^{-2}\ mol\times 78\ g/mol\\\\m=6.58\ g

Also,

No of moles = no of molecules/Avogadro number

N=n\times N_A\\\\N=8.437\times 10^{-2}\times 6.023\times 10^{23}\\\\N=5.08\times 10^{22}\ \text{molecules}

Hence, there are 5.08\times 10^{22}\ \text{molecules of}\ C_6H_6

An object accelerates 8.2 m/s2 when a force of 20.1 Newton's is applied to it. What is the mass of the object?
Shalnov [3]
Hey it's me again haha!

the answer to your question is:

answer: so f=20.1

a=8.2

m=?

f=ma

20.1 = 8.2*m in

20.1/8.2=m

so the answer is around 2.45 something!
also i'm sorry this question had be stumbled!
