Answer:
125g × 1 mol/16 grams = 7.81 × avogadros #
Answer:
A physical property that depends on the sample size
Explanation:
The equation N2+H2= NH3 is balanced. This is because N2 + 3H^2 ➡️ 2NH^3
Calculating for the moles of H+
1.0 L x (1.00 mole / 1 L ) = 1 mole H+
From the given balanced equation, we can use the stoichiometric ratio to solve for the moles of PbCO3:
1 mole H+ x (1 mole PbCO3 / 2 moles H+) = 0.5 moles PbCO3
Converting the moles of PbCO3 to grams using the molecular weight of PbCO3
0.5 moles PbCO3 x (267 g PbCO3 / 1 mole PbCO3) = 84.5 g PbCO3
