The volume of the substance is 61.4 litres.
Explanation:
Specific density is the ratio of density of a substance at a given temperature with the density of reference substance.
Data given:
mass = 750 grams
specific gravity = 12.2
volume=?
The formula to be used:
Specific gravity = 
suppose the other substance is water so its density is 1g/ml at 4 degrees
Putting the values to the equation:
density of the object = 1 x12.2
density of the substance = 12.2
Now using the formula:
density = 
putting the values in the equation:
volume = 
= 61.4ml is the volume of the substance.
Answer:
The mass of I₂ produced is 66.43 g.
Explanation:
In a stoichiometry exercise we follow a series of steps.
Step 1: Write the balanced equation
2 CuCl₂ + 4 KI ⇄ 2 CuI + 4 KCl + I₂
Step 2: Look for the relationship between the data we have and the one we are looking for
According to the balanced equation, when 2 moles of CuCl₂ react 1 mole of I₂ is formed. This is the first relation. Secondly, we know that the molar mass of 253.80 g/mol, that is, every mole of I₂ has a mass of 253.80 g. This is the second relation.
Step 3: Apply relations to the data we have

Answer:
I'm glad you asked!
Explanation:
The answer is the first one.Pure substances are substances that are mixed together.The picture shows that they are pure substances.Pure substances are always combined.So that makes it the first one.
