The two isotopes of chlorine are 3517Cl and 3717Cl. Which isotope is the most abundant?

nikklg [1K]

Answer:

The most abundant isotope is ³⁵Cl₁₇.

Since the average atomic mass of Cl is 35.45 g/mole, so the most abundant one is that one near this number, ³⁵Cl₁₇.

³⁵Cl₁₇ is found by 75 % and ³⁷Cl₁₇ is found by 25 % by a ratio 3:1.

How many moles of atoms are in 6.00 g of 13C?

Lyrx [107]

Answer: 0.462 moles

Explanation: 13C indicates an isotope of carbon and its mass number is 13. It means the mass of 1 mol of 13C is 13 gram.

The question asks to calculate the number of atoms present in 6.00 grams of 13C.

To calculate the number of moles we divide the given grams by the mass of 1 mol of the element. The set could be shown easily using dimensional analysis as:

$6.00gram(\frac{1mol}{13gram})$

= 0.462 moles

So, there will be 0.462 moles of atoms in 6.00 grams of 13C.
