KCl: 74.5g/mol
Molarity = mol/Liters
Since you are given 0.750L and 1.50M, we can plug it into the molarity formula and solve for moles.
1.50M = x mol/0.750L
X = 1.125 moles of KCl needed
You asked for grams so let’s convert the moles of KCl to grams:
1.125 mol x (74.5g/mol) = 83.8g KCl
There are 18 atoms in 1.5 moles of Zinc
.07! you divide 7 by 100%
Answer:
With less energy at higher trophic levels, there are usually fewer organisms as well
Explanation: Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
Answer:
1.Velocity and pitch
2.The unit of vibration is hertz. The number of oscillations of an oscillating body per second is known as frequency. Complete step by step answer: The time taken by a vibrating body to complete one vibration is time period.
3.Frequencies above 20,000 Hz are known as ultrasound.
