Answer:- Volume of the 5.0 carat diamond is 
.
Solution:- It is a unit conversion problem. Need to convert carat to grams and then using grams and density the volume could easily be calculated.
We have 5.0 carat diamond and asked to calculate it's volume. Density of diamond is given as 
and 1 carat = 0.200 g. Let's do this step by step:
First step is the conversion of carat to grams:
= 1.0 g
In second step, grams are converted to volume using the given density as:
So, the volume of the 5.0 carat diamond is .
Answer: 0.024 M
Explanation:
According to the neutralization law,
where,
= molarity of stock solution = 0.12 M
= volume of stock solution = 20.0 ml
= molarity of diluted solution = ? M
= volume of diluted solution = 100.0 ml
Putting in the values we get:
Therefore, the concentration of the resulting solution is 0.024 M.
You must add 7.5 pt of the 30 % sugar to the 5 % sugar to get a 20 % solution.
You can use a modified dilution formula to calculate the volume of 30 % sugar.
<em>V</em>_1×<em>C</em>_1 + <em>V</em>_2×<em>C</em>_2 = <em>V</em>_3×<em>C</em>_3
Let the volume of 30 % sugar = <em>x</em> pt. Then the volume of the final 20 % sugar = (5 + <em>x</em> ) pt
(<em>x</em> pt×30 % sugar) + (5 pt×5 % sugar) = (<em>x</em> + 5) pt × 20 % sugar
30<em>x</em> + 25 = 20x + 100
10<em>x</em> = 75
<em>x</em> = 75/10 = 7.5
Chemsits identify elements and compounds by using the Periodic Table. All elements have Atomic Numbers, Chemical Names, Atomic Mass, Period, and are usually colored and put into their group.
Im not sure but I think it’s the second one
