Answer:
14.06 M
Explanation:
Molarity: moles of a solution / liters of a solution
We convert 569ml into liters for the equation by dividing milliliters by 1000.
569/1000 = 0.569L
Now that we have Liters we can do moles of a solution / liters of a solution:
8 / 0.569 = 14.06 M
Answer:
<h2>119.87 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question we have
We have the final answer as
<h3>119.87 cm³ to two decimal places</h3>
Hope this helps you
Answer:
True
Explanation:
Yes this statement is true.
In a physical change, some of the physical properties of the substance may be altered and the chemical composition remains the same.
The density of sucrose is 1.58 g/ cm³
<em><u>Calculation</u></em>
Step 1 : calculate the volume of benzene
volume = mass/density
mass of benzene = total mass - mass of sucrose
=17.33 g - 9.35 g =7.98 g
volume = 7.98 / 0.879 =9.08 cm³
Step 2: calculate the volume of sucrose
volume of sucrose= Total volume - volume of benzene
Total volume = 15 ml =15 cm³
volume of sucrose is therefore = 15 cm³ - 9.08 cm³=5.92 cm³
Step 4: calculate the density of sucrose
density = mass/volume
= 9.35 g / 5.92 cm³ = 1.58 g/cm³
