What is the volume (in liters) occupied by 49.8 g og HCl at STP
Anon25 [30]

Using ideal gas equation,

P\times V=n\times R\times T

Here,

P denotes pressure

V denotes volume

n denotes number of moles of gas

R denotes gas constant

T denotes temperature

The values at STP will be:

P=1 atm

T=273 K

R=0.0821 atm L mol ⁻¹

Mass of HCl given= 49.8 g

Molar mass of HCl given=36.41

Number of moles of gas, n= \frac{Given mass of the substance}{Molar mass of the substance}

Number of moles of gas, n= \frac{49.8}{36.46}

Number of moles of gas, n= 1.36

Putting all the values in the above equation,

V=\frac{1.36\times 0.0821\times 273}{1}

V=30.6 L

So the volume will be 30.6 L.

The mass spectra of alcohols often fail to exhibit detectable M peaks but instead show relatively large ________ peaks.
nirvana33 [79]

Answer: M-18

Explanation:

The mass spectra of alcohols often fail to exhibit detectable M peaks but instead show relatively large __M-18___ peaks.

Mass spectroscopy is used to determine the molecular mass and molecular formula of a sample.

When the mass spectra of alcohols do not show detectable M peaks, they show relatively large M-18 peaks.
