Answer:
The answer to your question is: 2.20 x 10 ²³ molecules
Explanation:
Data
mass = 45.7 g
molecules of CF₂Cl₂ = ?
Process
1.- Calculate the mass number of CF₂Cl₂
C = 12 F =2 x 19 Cl = 2 x 35.5
total = 12 + 38 + 71
total = 121 g
2.- Use the Avogradro's number to solve the problem
121 g ------------------- 6.023 x 10²³ molecules of CF₂Cl₂
45.7 g --------------- x
x = (45.7 x 6.023 x 10²³) / 121
x = 2.75 x 10²⁵ / 121
x = 2.20 x 10 ²³ molecules
To determine the mass of the iceberg, we simply multiply the density with the volume. Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. Remember that the units should be homogeneous. We calculate as follows:
mass = density x volume
mass = 0.92 g /cm^3 ( 9470 ft^3) ( 30.48 cm / 1 ft )^3 ( 1 kg / 1000 g ) = 265.55 kg

Answer:
Atoms
Explanation:
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.
CCAUCG is the nucleotide sequence of an mrna strand that has been transcribed from the dna sequence ggtagc.
<h3>
What is a nucleotide sequence?</h3>
- Transfer RNAs interact with the ribosome system to translate a nucleic acid sequence, known as a messenger RNA or mRNA, into the protein it encodes.
- Transfer RNAs partition the nucleic acid sequence into triplet codons, each of which specifies one amino acid, by binding to three nucleotides at once.
- The sequence does not contain punctuation signals to indicate which reading frame should be used, hence the nucleic acid can be read in three different phases or reading frames depending on the point at which division into codons begins.
- An addition or deletion in the nucleic acid sequence that changes the translation process from one reading frame to another is known as a frameshift mutation.
