One can accurately measure hydrogen in a given sample using techniques such as gas chromatography, mass spectrometry, or titration. These methods involve separating and quantifying the amount of hydrogen present in the sample.
One can test for hydrogen in a given sample by using a hydrogen gas sensor or by conducting a flame test, where hydrogen gas is ignited to produce a characteristic pop sound.
To test for hydrogen in the given substance, a dry sample is needed. Burn it in excess of oxygen. If the vapour turns white copper sulfate into blue colour, it indicates that there is water in present in the vapour. Hence, the organic compound contains hydrogen.
Mass of C= 80.0 g Mass of H =20.0 g
the answer is 4.0 g hope i helped! :)
A mole is used in chemistry as a unit of measurement to quantify the amount of a substance in a given sample. It represents a specific number of particles (6.022 x 1023) and allows chemists to easily compare and calculate the amount of different substances in reactions.

The caffeine content in a beverage can be accurately measured using a process called chromatography, which separates and quantifies the different components in the drink. This method involves comparing the caffeine peak in the beverage sample to a known caffeine standard to determine the exact amount present.
One can accurately measure sunlight in a given area using a device called a pyranometer, which measures the total solar radiation received on a horizontal surface. This device can provide data on the intensity and duration of sunlight in a specific location.
Mass of C= 80.0 g Mass of H =20.0 g
a sample is a sample sized piece given... a sample size is the amount given in one sample
One can accurately measure potential energy in a given system by calculating the height of an object above a reference point and multiplying it by the force of gravity and the mass of the object. This formula, PE mgh, helps determine the potential energy stored in the object.
the answer is 4.0 g hope i helped! :)
It is impossible to determine the percentiles if you are given only the sample mean since percentiles are a measure of the spread of the data; the mean gives no information on that.
To accurately measure the frequency in hertz (Hz) of a signal or waveform, one can use an oscilloscope or a frequency counter. These devices can analyze the signal and provide a numerical value for its frequency in hertz.
One can accurately measure charge in a given system by using an instrument called a Coulomb meter, which can detect and quantify the amount of charge present in the system. This device measures the flow of electric current, which is directly related to the amount of charge passing through a circuit. By using a Coulomb meter, one can determine the precise amount of charge in a given system.
The concentration of H+ ions is given by pH, a term that stands for potential Hydrogen (it's called potential hydrogen because hydrogen ions can potentially become hydrogen gas).
