Answer:3
Explanation:
The three moles of S are divided by the moles in your product in this case 1 (AlS)
3/1=3
I had this question before if your answer choice D) says it had more mass than the rest of the atom. then that will be it :)
There needs to be the story so that i can work with the 1st question
There are 5.4 × 10^23 atoms in 12 g NaOH
.
<em>Step 1</em>. Convert <em>grams of NaOH to moles of NaOH
</em>
Moles of NaOH = 12 g NaOH × (1 mol NaOH /40.00 g NaOH)
= 0.300 mol NaOH
<em>Step 2</em>. Convert <em>moles of NaOH to formula units (FU) of NaOH
</em>
FU of NaOH = 0.300 mol NaOH × (6.022 × 10^23 Fu NaOH/1 mol NaOH)
= 1.81 × 10^23 FU NaOH
<em>Step 3</em>. Convert <em>FU of NaOH to atoms
</em>
1.81 × 10^23 FU NaOH × (3 atoms/1 FU NaOH) = 5.4 × 10^23 atoms
