Explanation:
The mass of bromine is 79.904, and since there are two of them in the Calcium Bromide molecule, we'll multiply it by 2 to get 159.808. Dividing that by the full mass of the molecule then multiply it by 100 will give you the answer.
Answer:
P = 133.4 atm
Explanation:
Given data:
Mass of helium = 988 g
Volume = 45.0 L
Temperature = 23°C (23+273= 296 K)
Pressure of cylinder = ?
Solution:
Number of moles of helium:
Number of moles = mass/ molar mass
Number of moles = 988 g/ 4 g/mol
Number of moles = 247 mol
Pressure:
PV = nRT
P = nRT/V
P = 247 mol × 0.0821. atm. L/mol. K × 296 K / 45 L
P = 6002.5 / 45 L
P = 133.4 atm
Answer:
Its responsible for the process known as translation, or the process our cells use to make proteins.They are also responsible for reading the order of Amino acids and linking them together.
Hope it helps!
Answer:
Ribosomes preform biological synthesis. (mRNA Translation). They also link amino acids together to form polypeptide chain.
