In a fish tank, the ratio of orange fish to blue fish is 4:3. Which statement is true?3/4 of the fish in the tank are blue
if there is a total of 56 fish in the tank,than 24 of the fish are orange
The number of orange fish is 1 1/3 times the number of blue fish.
If there are 12 blue fish in the tank, then there are 18 orange fish.
Answers
Answer:
b) The number of orange fish is 1 1/3 times the number of blue fish.
Step-by-step explanation:
We are given the following information in the question:
In a fish tank, the ratio of orange fish to blue fish is 4:3.
Thus, we can write:
Thus, total number of fishes in the tank can be written as:
a) False
If there is a total of 56 fish in the tank,than 32 of the fish are orange
Total number of fish = 56
b)True
c) False
If there are 12 blue fish in the tank, then there are 16 orange fish.
Number of blue fish = 12
4/7 are orange, 3/7 are blue
The number of orange fish is 1 1/3 times the number of blue bc 4/3 and 4/7÷3/7 equals 1 1/3

What is molar mass?
Molar mass is the mass equivalent of Avogadro's number of atoms of an element, or Avogadro's number of molecules of in a chemical compound.
Given:
The number of molecules in the sample of N₂I₆ = 3.30 X 10²³
We need to find: the number of grams in the given sample,
One mole of a substance has exactly 6.022 X 10²³ elemental units. These elemental units can be molecules, ions, or atoms depending on the substance.
If 6.022 X 10²³ molecules of N₂I₆ constitute 1 mole of the substance,
Then 1 molecule will constitute 1/6.022 X 10²³ moles of the substance.
Therefore, 3.30 X 10²³ molecules of N₂I₆ will have 3.30 X 10²³ / 6.022 X 10²³ moles
= 3.300 / 6.022
= 0.55 moles
We know that the mass of 1 mole of a substance is equal to its molar mass.
The molar mass of N₂I₆ = 2 X Molar mass of N + 6 X Molar mass of I
= 2 X 14 + 6 X 127
= 28 + 762
= 790 g
Thus, 1 mole of N₂I₆ will weigh 790g
Therefore, 0.55 moles will weigh 790 X 0.55 g
= 434.5 g
Hence, the number of grams in the given sample is 434.5 g.

Step-by-step explanation:Absolute value is a number's distance away from zero. For example, on a number line, -9 is 9 spaces away from zero. So, the absolut value is 9. Similarly, the number 9 is also 9 spaces from zero, so the absolute value would be 9. 9 and -9 both have an absolute value of 9. I hope this is helpful!
