Answer:
1. d
2. b
3. d
4. e
5. a
explanation:
there's nothing else to explain
From the periodic table you know that Cl has a molar mass of 35.35 g/m. So if you just set up the dimensional analysis as so: (.46 moles Cl)*(35.45 grams Cl/1 mole Cl) and multiply out you get 16 grams of Cl if you follow the sig figs and 16.307 if you don't.
Moles of NH₃ : = 7.059
<h3>Further explanation</h3>
Given
120 g NH₃
Required
moles NH₃
Solution
The mole is the number of particles contained in a substance
<em>1 mol = 6.02.10²³
</em>
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
So for 120 g (molar mass of NH₃ = 17 g/mol) :
= 120 g : 17 g/mol
= 7.059
The answer should be d but it could be c
