Molar mass of Li = 6.9 g/mol
6.9 g -------------------- 6.0x10²³ atoms
g -------------------- 2.75x10^21 atoms
6.0x10²³ g = 6.9 * (2.75x10^21)
6.0x10²³ g = 1.8975x10²²
g = 1.8975x10²² / 6.0x10²³
x = 0,0317 g
answer b
hope this helps!.
Answer:
im pretty sure the answer is b
Answer:
The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Therefore, the child could not possibly be of blood type O.
