Answer:
See Below.
Explanation:
Recall that molarity is defined by moles of solute over liters of solution (mol/L).
Therefore, to make 90.0 mL of 2.0 M MgSO₄, we will need:
Convert this amount to grams. The molecular weight of MgSO₄ is 120.38 g/mol:
Therefore, to make the solution, we can add 22 grams of MgSO₄ into a graduated cylinder, then mix and dilute the solution with distilled water until we reach 90.0 mL.
Answer:
<h2>1.43 g/cm³</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 84.7 g
volume = 59.3 cm³
We have
We have the final answer as
<h3>1.43 g/cm³</h3>Hope this helps you
