Answer:
0.373 moles of ammonium carbonate
Explanation:
To solve this question we must find the molar mass of ammonium carbonate. With the molar mass and the mass we can find its moles, as follows:
(NH₄)₂CO₃ contains: 2 moles N, 8 moles H, 1 mole C, 3 moles O. Molar mass:
2N = 14.0g/mol*2 = 28.0
8H = 1.0g/mol*8 = 8.0
1C = 12.0g/mol*1 = 12.0
3O = 16.0g/mol*3 = 48.0
Molar mass: 28.0 + 8.0 + 12.0 + 48.0 = 96.0g/mol
The moles of ammonium carbonate in 35.8g are:
35.8g * (1mol / 96.0g) =
<h3>0.373 moles of ammonium carbonate</h3>
<span>On a molar a basis, the most effective bleaching agent kbro3 has more oxygen, but due to the bromine, it would make things look yellowish. The bromine would counteracts the bleaching effect. As we all know, bleach is naocl or hypochlorite</span>
Melted rock and minerals under the earths crust are called magma
Total volume of the solution formed will be 32.5 liters
Given:
Molarity of solution = 0.0200 m
mass of nacl = 38.0 grams
To Find:
total volume of the solution
Solution: Molarity is defined as the amount of solute present in 1 L of solution. The equation used to determine molarity of the solution follows:
M = given mass of nacl/molar mass of nacl*1/volume of solution
volume of solution = given mass/molar mass*1/molarity
volume = 38/58.5*1/0.02 = 32.5
Hence, volume of solution = 32.5 litres
