Answer: Charles' Law
Explanation: At constant pressure, Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale. [0 Kelvin = 0 Liters gas]
Answer: Quantity required for a 0.125 mg dose is 2.5 ml
Explanation:
Given : Available concentration of Digoxin Elixir = 0.05 mg/ml.
That is 0.05 mg is present in 1 ml of the solution. We need to find quantity required for a 0.125 mg dose.
This can be found using unitary method.
For 0.05 mg, the quantity required is = 1ml
Thus for 1 mg , the quantity required is = ![\frac{1}{0.05}\times 1=20ml](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B0.05%7D%5Ctimes%201%3D20ml)
For 0.125 mg , the quantity required is = ![\frac{20}{1}\times 0.125=2.5ml](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B1%7D%5Ctimes%200.125%3D2.5ml)
Thus quantity required for a 0.125 mg dose is 2.5 ml
The answer is: the mass of 6.02 x 1023 representative particles of the element.
The base SI unit for molar mass is kg/mol, but chemist more use g/mol (gram per mole).
For example, molar mas of ammonia is 17.031 g/mol.
M(NH₃) = Ar(N) + 3 · Ar(H) · g/mol.
M(NH₃) = 14.007 + 3 · 1.008 · g/mol.
M(NH₃) = 17.031 g/mol.
The molar mass (M) is the mass of a given substance (in this example ammonia) divided by the amount of substance.
