Calculate the mass of atoms of carbon and 3 molecules of hydrogen​
PSYCHO15rus [73]

The mass of atoms of carbon and 3 molecules of hydrogen​ : 18 g/mol

<h3>Further explanation </h3>

An atomic mass unit ( amu or "u") is a relative atomic mass of 1/12 the mass of an atom of carbon-12.  

The molar mass(molecular mass-formula mass-molecular weight(MW)) of a compound is the sum of the relative atomic mass (Ar) of the constituent elements of the compound

Can be formulated :  

M AxBy = (x.Ar A + y. Ar B)  

The mass of atom of Carbon(C)⇒Ar = 12 g/mol

The mass of 1 molecule of Hydrogen - H₂(MW) : 2 g/mol

The mass of 3 molecules of Hydrogen : 3 x 2 = 6 g/mol

So the mass of atoms of carbon and 3 molecules of hydrogen​ :

\tt 12+6=18~g/mol

brilliants [131]

Answer:

Hence the evaporation rate in pints per minute is 0.001583.

Explanation:

Now,

1.5 gallons of paint are used.

It has 5% solid, so total 95% of 1.5 gallon can evaporate(only the solvent part will evaporate).

95% of 1.5 gallon=(95/100)*1.5 = 1.425 gallons.

1gallon = 8 pints.

So 1.425 gallons=8*1.425 pints

=11.4 pints.

Evaporation requires 2 hours. That is 3600*2 seconds = 7200 seconds.

So evaporation rate= 11.4 pints/7200 seconds.

=0.001583 pints per second
