The number of molecules in 9 g of ice (H2O) is
- A
6.02 x 1024
- B
6.02 x 1023
- C
3.01 x 1024
- D
3.01 x 1023
Water has a mass of 18g (16+2). So, 9g of ice(H2O) means 0.5 mol. 1 mol has a 6.02x1023 number of molecules, so 0.5 mol will have a 3.01x1023 number of molecules.
As it is numerical, it can have only one possible answer.
Water has a mass of 18g (16+2). So, 9g of ice(H2O) means 0.5 mol. 1 mol has a 6.02x10^23 number of molecules, so 0.5 mol will have a 3.01 x 1023 number of molecules.
As it is numerical, it can have only one possible answer.
