what volume of water will contain 2.4 Na of neutrons ? ( where Na = Avogadro number = 6.022 × 10²³ ) |
|
Answer» Answer: Correct option is B 10N a
The density of WATER is 18 G/mol. 18 mL of water corresponds to 18 g or 1 mole. They contain N a
(Avogadro's NUMBER) of molecules. Each water molecule contains total 2+8=10 electrons (2 from 2 H ATOMS and 8 from ONE O atom). Hence, 18 mL of water will contain 10 N a
electrons. |
