Question

just for fun, lets calculate how many agno₃ molecules are in those 0.100 moles. remember that avogadros number is nₐ = 6.02214 × 10²³.
a) 6.02 × 10²⁴ agno₃ molecules
b) 6.02 × 10²² agno₃ molecules
c) 6.02 × 10²³ agno₃ molecules
d) 0.100 molecules

Explanation:

Step1: Recall the formula

The number of molecules $N$ is given by $N = n\times N_A$, where $n$ is the number of moles and $N_A$ is Avogadro's number.

Step2: Substitute the values

Here, $n = 0.100$ moles and $N_A=6.02214\times 10^{23}\text{ molecules/mol}$. So $N=0.100\times6.02214\times 10^{23}$.

Step3: Calculate the result

$0.100\times6.02214\times 10^{23}=6.02214\times 10^{22}\approx6.02\times 10^{22}$ molecules.

Answer:

B. $6.02\times 10^{22}\text{ AgNO}_3$ molecules
