Answer:
1.28 g
Explanation:
Mass of anhydrous compound/molar mass of anhydrous compound = mass of hydrated compound/ molar mass of hydrated compound
Mass of anhydrous compound = ?
Mass of hydrated compound = 2g
Molar mass of anhydrous compound= 160 g/mol
Molar mass of hydrated compound = 250 g/mol
x/160 = 2/250
250x = 2 ×160
x= 2 × 160/250
x= 1.28 g

Answer:
the pressure of gas is 100.0 the volume is 500.0
Explanation:
The molarity of a solution is found to be 10 M.
Explanation:
- Molarity of a solution = <u>moles solute</u>
Litres solution
5
- Molarity of a solution = 10 M
