Convert 18.6 L of neon gas at STP to atoms. 1.What is the coefficient of the scientific notation answer? 2.What is the exponent of the scientific notation answer? 3.How many significant figures are there in the answer?
4.What is the right most significant figure in the answer ?

See explanation

Explanation:

1 mole of Ne occupies 22.4 L

x moles of Ne occupies 18.6 L

x = 1 mole *  18.6 L/22.4 L

x = 0.83 moles

1 mole contains 6.02 * 10^23 atoms

0.83 moles occupies  0.83 moles *  6.02 * 10^23 atoms/1 mole

= 4.9966 * 10^23 atoms = 5.0  * 10^23 atoms

the coefficient of the scientific notation answer =5.0

the exponent of the scientific notation answer = 23

significant figures are there in the answer = 5

the right most significant figure in the answer = 1
