Given the unbalanced equation: ___ca(oh)2 + ___(nh4)2so4 → ___caso4 + ___nh3 + ___h2o what is the sum of the coefficients when t
2 answers:
<span>Ca(OH)2 + (NH4)2SO4 </span>→<span> CaSO4 + 2NH3 + 2H2O
That is the balanced equation.
The coefficients represent the amount of moles for that reactant. There is 1 mole of Calcium Hydroxide, 1 mole of Ammonium Sulfate, 1 mole of Calcium Sulfate, 2 moles of Ammonium, and 2 moles of water.
Now add all the coefficients/moles.

Answer:
0.0250 g
Explanation:
Step 1: Determine the molar mass of Vitamin C.
The molar mass is the mass in grams corresponding to 1 mole. In order to calculate the molar mass of vitamin C (C₆H₈O₆) we need to add the molar masses of the elements that compose it.
M(C₆H₈O₆) = 6 × M(C) + 8 × M(H) + 6 × M(O)
M(C₆H₈O₆) = 6 × 12.01 g/mol + 8 × 1.01 g/mol + 6 × 16.00 g/mol
M(C₆H₈O₆) = 176.14 g/mol
Step 2: Calculate the mass corresponding to 0.000142 mol of vitamin C.
