Explanation:
Given
(a) to (d)
Required
Determine whether the given parameters can calculate the required parameter
To calculate either Density, Mass or Volume, we have
(a) 432 g of table salt occupies 20.0 cm^3 of space
Here, we have:
The above can be used to calculate Density as follows;
(b) 5.00 g of balsa wood, density of balsa wood : 0.16 g/cm^3
Here, we have:
This can be used to solve for Volume as follows:
(c) 32 cm^3 sample of gold density of 19.3 g/cm^3
Here, we have:
This can be used to calculate Mass as follows:
(d) 150 g of iron, density of Iron = 79.0 g/cm^3
Here, we have
This can be used to calculate volume as follows:

Answer:
Heterogenous
Explanation:
Mud is a mixture of water and soil
The process of separating alcohol from water can be done in several different ways. The most familiar method is through heating the blended liquid. Since alcohol has a lower boiling temperature than water, it will rapidly become steam. It can then be condensed into a separate container. You can also freeze the alcoholic mixture, which allows for partial removal of the nonalcoholic components; what remains will be more rich in alcohol. Use ordinary table salt to separate isopropyl alcohol from water. The result will be a condensed isopropyl alcohol, not a drinking alcohol.
Answer:
Tc^(+7) - 2.35*10^-5M
PO4(^-3) - 5.50*10^-5M
Explanation:
Tc3(PO4)7 <---> 
1 mol 3 mol 7 mol
7.85 X 10^-6 M 3*7.85*10^-6M 7*7.85*10^-6M
2.35*10^-5M 5.50*10^-5M
