Question

100. The volume occupied by 10 grams of hydrogen gas at STP is
(1)
112 litres
(2]
11.2 litres
(3) 224 litres
224 లీటర్లు
(4) 22-4 litres
22-4 లీటర్లు
112 లీటర్లు
11.2 లీటర్లు​

Answer 1

Answer:

112 L

Explanation:

First, we calculate Mole (n) of H2-

\begin{gathered}n \: = \frac{mass}{gram \: atomic \: mass} \\ \\ = \frac{10}{2} \\ \\ n \: = 5 \\ \\\end{gathered}n=gramatomicmassmass=210n=5

Now,

\begin{gathered}volume \: = mole \times 22.4(in \: litres) \\ \\ 5 \times 22.4 \\ \\ 112 \: L \:\end{gathered}volume=mole×22.4(inlitres)5×22.4112L
