88 foot per second. 
5280 feet = 1 mile

5280 × 60 = 316800

316800 feet per hour

3600 seconds = 1 hour

316800 feet per 3600 seconds

316800 ÷ 3600 = 88

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.
