<em>Answer:</em>
- The concentration of new solution will be 1×10∧-7 M.
<em>Solution:</em>
<em>Data Given </em>
given mass of fluoxymesterone =16.8mg = 0.0168 g
molar mass of fluoxymesterone = 336g/mol
vol. of fluoxymesterone = 500.0 ml = 0.500 L
Stock Molarity of fluoxymesterone = (0.0168/336)÷0.500 = 1×10∧-4 M
So applying dilution formula
Stock Solution : New Solution
M1.V1 = M2.V2
( 1×10∧-4 M) × (1×10∧-6 L) = M2 × 0.001 L
[( 1×10∧-4) × (1×10∧-6)]÷[0.001] = M2
1 × 10∧-7 = M2
<em>Result:</em>
- The concentration of new solution M2 will be 1 × 10∧-7
D = 0.2 g / ml = 0.2 g / cm³
For example, density of steel is 7.85 g / cm³.
Density of pure water is 1.0 g/cm³. An object which has a density < 1.0 g/cm³ will float in water.
Answer: Material that has a density of 0.2 g/ml ( 0.2 g/cm³ ) is good for making couch cushions.

The answer for the following question is mentioned below.
+3 
→2 
+2 
the equation is balanced.
Explanation:
The steps required to balance a chemical equation is:
Firstly,write the formula of the compound/substance.
Secondly,count the number of atoms in each element on each side of the equation
Thirdly,Adjust the co-efficient.Balance the atoms or the ions present in the greatest number.
You may do this by finding the lowest common multiple of two.
Continue systematically to balance the atoms or ions on the rest of the side (i.e.)on the other side.
Lastly,check the number of atoms each elements is same on both the sides
From the equation:
Before balancing the equation:
+ → +
After balancing the equation:
+3 →2 +2
Therefore the given equation is balanced.
Answer:
0.09 moles of Br₂
Explanation:
Bromine liquid it refers at Br₂ molecule which is liquid at room temperature.
Now to calculate the number of moles we use the following formula:
number of moles = mass (g) / molecular mass (g/mol)
For Br₂ molecule we have:
number of moles = 14.4 / 160 = 0.09 moles of Br₂
