Answer:
because nitrogen is fixed by bacteria and assimilated by plants
Explanation:
Answer:
78.15 g
Explanation:
Number of moles of C₇H₆O₃ that reacted = mass/molar mass = 57.6g/126 gmol-1
Number of moles of C₇H₆O₃ = 0.457 moles of C₇H₆O₃
From the reaction equation;
1 mole of C₇H₆O₃ yields one mole of aspirin
0.457 moles of C₇H₆O₃ yields C₇H₆O₃ of aspirin
Hence theoretical yield of aspirin = 0.457 moles × 180 gmol-1 = 82.26g of aspirin
% yield = actual yield/theoretical yield ×100
Actual yield= % yield × theoretical yield/100
Actual yield = 95.0 × 82.26/100
Actual yield = 78.15 g
Answer:
Ans: 5.8g
Explanation:
31.35L * 1mol/22.4L * 4.00g/1mol = 5.81g
According to www.healthline.com: “Magnesium stearate is an additive that's primarily used in medication capsules. It's considered a “flow agent.” It prevents the individual ingredients in a capsule from sticking to each other and the machine that creates the capsules. It helps improve the consistency and quality control of medication capsules.”

Mols is shorthand for molarity, a unit of measurement corresponding to moles/liter. A mole is just a number for example “ a dozen”. Mole is also spelled mol in chemistry so they do mean the same.
