Answer:
28 g/mol, N2
Explanation:
Given data:
Volume of gas = 5.0 L
Mass of gas = 6.3 g
Pressure = 1 atm
Temperature = 273 K
Molar mass of gas = ?
Solution:
We will calculate the density first.
d = mass/ volume
d = 6.3 g/ 5.0 L
d = 1.26 g/L
Molar mass:
d = PM/RT
M = dRT/P
M = 1.26 g/L× 0.0821 atm.L/mol.K × 273 K/ 1 atm
M = 28 g/mol
Molar mass of N₂ is 28 g/mol thus given gas is N₂.
The empirical formula for this would be FeS
Answer:
1.) The total possible combination of alleles for those genes in humans is approximately 70,368,744,177,664. This is trillions of times more combinations than the number of people who have ever lived. This accounts for the fact that nearly everyone, except m0n0zyg0tic twins, is genetically unique.
2.) A hom0zyg0us recessive allele c0mbination contains two recessive alleles and expresses the recessive phen0type. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r).
4.) If the alleles are heteryg0us recessive, the faulty allele would be recessive and not express itself. Instead, the person would be a carrier. If the alleles are heterozyg0us dominant, the faulty allele would be dominant.
