Question

calculate the no of hydrogen atoms in 9g of water?
​

Answer 1

Answer:

Answer: 9 is 1/2 of 18, meaning that 1/2 mole is present in 9 g of water. 1/2 * 6.022 *10^23 = 3.011 * 10^23 molecules H2O. However, if you want to know how many ATOMS are present in 3.011 *10^23, you must then multiply by 3 (2 hydrogen atoms and 1 oxygen atom per molecule), and get 9.033 * 10^23 atoms.

Answer 2

Answer:

in water hydrogen and water combine in 2:1 ratio
