Pressure raises the boiling point
Answer:
On genes within chromosomes
Explanation:
-The fur pattern is a genetic trait whose instruction is carried in the DNA's base sequence.
-These instructions are organized into genes and each gene is only responsble for the making of a functional product.
-Hence, the instructions are stored on genes within chromosomes.

Answer:
Mole fraction H2: 0.625
Mole fraction O2: 0.375
Molecular weight: 13.25g/mol
Mass fraction H2: 0.094
Mass fraction O2: 0.906
Explanation:
Moles fraction is defined as the ratio between moles of a substance and total moles presents in a mixture:
<em>Mole fraction H2 = 5kmol / (5kmol + 3kmol) = </em><em>0.625</em>
<em>Mole fraction O2 = 3kmol / (5kmol + 3kmol) = </em><em>0.375</em>
<em />
Molecular weight is defined as the mass per mole of substance:
Mass H2 = 5kmol * (2kg / kmol) = 10kg
Mass O2 = 3kmol * (32kg / kmol) = 96kg
<em>Molecular weight:</em>
106kg / 8kmol = 13.25g/mol
In the same way, mass fraction is the ratio between mass of a substance and total mass of the mixture:
<em>Mass fraction H2 = 10kg / (10kg + 96kg) = </em><em>0.094</em>
<em>Mass fraction O2 = 96kg / (10kg + 96kg) = </em><em>0.906</em>
