Molar mass HCl : <span>36.5 g/mol
</span>
number of moles:

n  = mass solute / molar mass

n = 1.56 / 36.5

n =0.0427 moles

Volume in liters : 26.8 mL / 1000 => 0.0268 L

therefore:

Molarity  = moles solute / volume 

Molarity =  0.0427  / 0.0268 => 1.593 M

Phosgene is a highly toxic gas made up of carbon, oxygen, and chlorine atoms. Its density at 1.05 atm and 258C is 4.24 g/L. (a)
VikaD [51]

Answer:

Molar mass = 99 g/mol

Explanation:

Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2

The molar mass is given as the sum off the individual atomic mass of the elements in the compound.

Molar mass = C + O + 2Cl

Molar mass = 12 + 16 + 2(35.5)

Molar mass = 99 g/mol

Please help me what is the answer
Sladkaya [172]

There are 20.8 moles of propanol

<h3>Further explanation  </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

1.2 x 10⁵ molecules of propanol

\tt \dfrac{1.25\times 10^{25}}{6.02\times 10^{23}}=20.8~moles
