Sagot :
Block of ice of mass 59.5g contains 19.87 ×10²³molecules and 39.75×10²³ atoms.
Molecular mass of Water is 18g/mol
No. of moles = Given mass /Molecular mass
No. of moles of water = 59.5/18 (Given, mass of block of ice is 59.5g)
= 3.3moles.
1mol of water contains 6.023×10²³ molecules of water.
Then,3.3 moles of water contains ,
3.3× 6.023×10²³= 19.87 ×10²³molecules.
1mol of water (H₂O) contains,2× 6.023×10²³ atoms of hydrogen
Then, 3.3 moles of water contains,
2×3.3× 6.023×10²³ = 39.75×10²³ atoms of hydrogen.
Thus, the molecules and atoms present in the block of ice of mass 59.5g is 19.87 ×10²³molecules and 39.75×10²³ atoms respectively.
