Answer:
A) 3.59 cm
Explanation:
Given that :-
The density of the gold ingot = 
Given that:- Mass = 5.50 lbs
Also, considering the conversion of lbs to g as shown below:-
1 lb = 453.592 g
Thus,
Mass = 
= 2494.756 g
The volume = Length*Breadth*Height
Given that:- Length = 12.0 cm , Breadth = 3.00 cm
Considering the expression for density as:-
Solving for height, we get that:-
Height=3.59 cm
Alleles are inside a gene and genes are made up by alleles. Also, a gene is DNA, so the allele is like piece of DNA inside a gene<span>.

(i) We start by calculating the mass of sugar in the solution:
mass of sugar = concentration × solution mass
mass of sugar = 2.5/100 × 500 = 12.5 g
Then now we can calculate the amount of water:
solution mass = mass of sugar + mass of water
mass of water = solution mass - mass of sugar
mass of water = 500 - 12.5 = 487.5 g
(ii) We use the following reasoning:
If 500 g solution contains 12.5 g sugar
Then X g solution contains 75 g sugar
X=(500×75)/12.5 = 3000 g solution
Now to get the amount of solution in liters we use density (we assume that is equal to 1):
Density = mass / volume
Volume = mass / density
Volume = 3000 / 1 = 3000 liters of sugar solution
