That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Water's heat of vaporization is around 540 cal/g at 100 °C, water's boiling point.
Answer:
98 g/mol
Explanation:
atomic mass for hydrogen=1
atomic mass for sulphur=32
atomic mass for oxygen=16
atomic mass for sulphuric acid=2H + S + 4O
=2x1 + 32 + 4x16
2+32+64=34+64
=98g/mol
Answer:
Explanation:
