6H2O represents 6 molecules of water
<h2>Relative Humidity</h2>
Explanation:
- Humidity is the amount of moisture content present in the atmosphere.
Humidity is of two types:
- Absolute humidity.
- Relative humidity.
- Absolute humidity is the ratio of the amount of moisture content in the air to the unit volume of the air.
- Relative humidity can be derived as the ratio of moisture content in the air to the maximum amount of moisture that the air constitutes.
- Hence, the required answer is Relative humidity.
Answer: The differences is Air masses cover over thousands and hundreds and millions of square kilo. A front is a boundary which two air masses but different temperature and moisture content meet.
Explanation:
Answer:
Formula of EPSOM salt = MgSO4.7H2O
molecular mass of MgSO4.7H2O = atomic mass of Mg + atomic mass of S + 4 × atomic mass of O + 7 { 2 × atomic mass of H + atomic mass of O }
= 24 + 32 + 4× 16 + 7{ 2 × 1 + 16 } g/mol
= (24 + 32 + 64+ 126 ) g/mol
= 246 g/mol
molecular mass of total water = 7 × ( 2× atomic mass of H + atomic mass of O )
= 7 × 18 = 126 g/mol
now ,
% mass of H2O in EPSOM salt = {total molar mass of H2O/molar mass of Epsom salts }× 100
= {126/246 } × 100
= 12600/246
= 51.21 %
