Answer:</h3>
0.00106 mole
<h3>
Explanation:</h3>
- The number of moles of a compound is calculated by dividing the mass of the compound by its molar mass.
Assuming the formula of the compound given is Mg₂P₂O₇ (magnesium pyrophosphate)
Molar mass of Mg₂P₂O₇ = 222.55 g/mol
Mass of the compound = 236 mg or 0.236 g
Therefore;
Number of moles = 0.236 g ÷ 222.55 g/mol
= 0.0010604
= 0.00106 mole ( 3 sf)
Therefore, the number of moles of Mg₂P₂O₇ are 0.00106 mole
Answer:
The fertilizer ammonium sulfate, (NH4)2SO4, is prepared by the reaction of ammonia, NH3, with sulfuric acid: 2 NH3 (g) + H2SO4 (aq) (NH4)2SO4 (aq)
How many moles of ammonium sulfate are produced if 1.50 moles of ammonia react completely at STP? Answer: The balanced equation indicates that 2 moles of NH3 react to produce 1 mole of (NH4)2SO4.
1.50 moles NH3 x 1 mol (NH4)2SO4 = 0.750 moles (NH4)2SO4

Liquids and gases are fluids because they can be made to flow. The particles in these fluids can move from place to place. Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.
