Answer/explanation :
To calculate the number of mass, we use this formula
Number of mole = mass / molar mass
Since we are given the number of mole
Number of mole = 2.60mol
Mass = ?g
Molar mass of Li = 6.941g/mol
2.60mol = mass / 6.941 g/mol
Mass = 2.60 * 6.941
= 18.0466g
Therefore, the number of mass is 18.0466g
<u>Answer:</u> The molarity of anions in the solution is 0.0316 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Given mass of iron (II) chloride = 0.10 g
Molar mass of iron (II) chloride = 126.75 g/mol
Volume of solution = 50 mL
Putting values in above equation, we get:
1 mole of iron (II) chloride produces 1 mole of ions and 2 moles of ions
So, concentration of chloride ions (anions) in the solution =
Hence, the molarity of anions in the solution is 0.0316 M
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
Answer:
669,600,000MPH
divide 1,339,200,000 by two, since that's for two hours
You get
669,600,000MPH
