Answer:
<h2>mass = 50 g</h2>
Explanation:
Density of a substance can be found by using the formula
From the question
Density = 2.5 g/mL
volume = 20 mL
To find the mass substitute the values into the above formula and solve for the mass
That's
Making mass the subject we have
mass = Density × volume
mass = 2.5 × 20
We have the final answer as
<h3>mass = 50 g</h3>

Answer:
number of moles of NaCl produce = 12 mol
Explanation:
Firstly, we need to write the chemical equation of the reaction and balance it .
Na(s) + Cl2(g) → NaCl(s)
The balanced equation is as follows:
2Na(s) + Cl2(g) → 2NaCl(s)
1 mole(71 g) of chlorine produces 2 moles(117 g) of sodium chloride
6 mole of chlorine gas will produce ? mole of sodium chloride
cross multiply
number of moles of NaCl produce = 6 × 2
number of moles of NaCl produce = 12 moles
number of moles of NaCl produce = 12 mol
