Answer:
1.22 g/cm³
Explanation:
Density = mass ÷ volume
Mass = 10.04 grams
Volume = 8.21 cubic centimeters
Density = mass ÷ volume
= 10.04 ÷ 8.21
= 1.2228989037758 g/cm³
Approximately
1.22 g/cm³ to 2 significant figure.
The final answer should be approximated to 2 significant figure because the mass and volume of the objective given is in 2 significant figure
For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
<u>Answer:</u> The volume of stock solution of ammonia that is needed is 48.67 mL
<u>Explanation:</u>
To calculate the volume of stock solution, we use the equation:
where,
are the molarity and volume of the stock ammonia solution
are the molarity and volume of diluted ammonia solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution of ammonia that is needed is 48.67 mL
If each side of the equation has the same number of atoms of a given element, that element is balanced.
