Answer:
<h2>The answer is 29.7 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 2.7 g/mL
volume = 11 mL
The mass is
mass = 2.7 × 11
We have the final answer as
<h3>29.7 g</h3>
Hope this helps you
Answer: C
Explanation:
For this problem, we would use Charles's Law. We fill in what we are given and solve.
Charles's Law: 



Answer:
The answer to your question is: 58.4 g of NaCl
Explanation:
Data
Volume = 200 ml = 0.2 l
Concentration = 5M
MW = 58.4 g
mass NaCl = ?
Formula
Molarity = (# of moles ) / volume
# of moles = Molarity x volume
# of moles = 5 x 0.2
# of moles = 1
58.4 g ---------------------- 1 mol
x --------------------- 1 mol
x = (1 x 58.4) / 1
x = 58.4 g of NaCl
