Question
The average density of the universe as a whole is estimated as 3×10–29 g/ml. If we assume that the entire mass is only H atoms, then what is the average volume of space that contains one H atom?
Options
A.111.11 L
B.1.8 × 10−5 L
C.55.56 L
D.3.6 × 10−5 L
Solution
Volume of one H-atom = $\frac{1}{6 \times 10^{23} \times 3 \times 10^{- 29}} = 5.56 \times 10^{4}\text{ ml}$
