A. Molar Mass
Explanation:
Gram molecular mass is the mass in grams of one mole of a molecular substance. Gram molecular mass is the same as molar mass.
The percent yield of indigo : 79.6%
<h3>Further explanation</h3>
Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
2C₁₀H₁₁NO₄ + 2H₂O → C₁₆H₁₀N₂O₂ + 2C₂H₄O₂ + 4H₂O
Actual yield = 1.87 g
Theoretical yield = 2.35 g
The percent yield of indigo :
![\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\\%yield=\dfrac{1.87}{2.35}\times 100\%=\boxed{\bold{79.6\%}}](https://tex.z-dn.net/?f=%5Ctt%20%5C%25yield%3D%5Cdfrac%7Bactual%7D%7Btheoretical%7D%5Ctimes%20100%5C%25%5C%5C%5C%5C%5C%25yield%3D%5Cdfrac%7B1.87%7D%7B2.35%7D%5Ctimes%20100%5C%25%3D%5Cboxed%7B%5Cbold%7B79.6%5C%25%7D%7D)
