Answer:
Characteristics of the genetic code. The genetic code consists of 64 triplets of nucleotides. These triplets are called codons.With three exceptions, each codon encodes for one of the 20 amino acids used in the synthesis of proteins.
Explanation:
Answer:
the sucrose mass is 264.g
Explanation:
The computation of the sucrose mass is shown below;
The Molar mass of is 342.3 g/mol
And, the molar mass of is 18g/mol
The mass of be Y
Now
The moles of is
= Mass of ÷ molar mass of
= Y ÷ 342.3 mol
And,
The moles of is
= Mass of ÷ molar mass of
= 100.0 ÷ 18
= 5.56mol
Now
The molar fraction of is
= Moles of ÷ (moles of + moles of ) = 0.124
= (Y ÷ 342.3) ÷ [(Y ÷ 342.3) + 5.56] = 0.124
Y ÷ 342.3 = 0.124 × [(Y ÷ 342.3 + 5.56]
Y = 0.124 × Y + (0.124 × 5.56 × 342.3)
Y = 269.4 g
hence, the sucrose mass is 264.g
Solution :
We know, molecular mass of NH₃ is , M = 17 g/mol .
Number of moles of NH₃ in 7.2 × 10²⁴ are :
So, mass of NH₃ present in 11.96 moles is :
m = 11.96 × 17 gram
m = 203.32 gram
Hence, this is the required solution.
Answer:
a. pulley system reduces amount of effort to lift a object.
Explanation:
pulley system can be used to change the direction of force to lift an object if we use more than one pulley it can be used to lift the load easily
