How many moles of aspirin should have been produced if there was 100% yield?

This means that the reaction produces 0.01448 moles of aspirin. This represents the theoretical yield of the reaction, i.e. what you get for a reaction that has a 100% yield.

Why is yield of aspirin not 100?

Using the theoretical and actual you can calculate percent yield. Your value may vary from the theoretical value for a number of reasons. If it is above 100%, it may be because your aspirin was not completely dried. If it is below 100%, it may be because of sample loss when transferring to the weigh paper.

What should the percent yield of aspirin be?

The percent yield of the aspirin obtained from the experiment is 46.3% yield. The higher the yield percentage, the higher the purity of the aspirin will be.

How do you calculate moles of aspirin?

Multiply the number of each type of atom by its molecular weight and then sum the products. In the case of aspirin, the molecular weights of carbon, hydrogen and oxygen are 12.01, 1.01 and 16.00 amu, respectively. The molecular weight of aspirin is therefore 9(12.01) + 8(1.01) + 4(16.00) = 180.17 amu.

What is the most number of moles of aspirin than an be made from one mole of salicylic acid?

The equation for this reaction is: C7H6O3 + C4H6O3 → C9H8O4 + CH3COOH Calculate the maximum mass of aspirin that could be made from 100 g of salicylic acid. This reaction is a 1:1 ratio of salicylic acid to aspirin, meaning 1 mole of salicylic acid makes a maximum of 1 mole of aspirin.

Can you get 100% percent yield?

It’s possible for percent yield to be over 100%, which means more sample was recovered from a reaction than predicted. This can happen when other reactions were occurring that also formed the product.

Why is it not possible to have more than 100% yield?

The percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage. … However, percent yields greater than 100% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.

How Is percent yield calculated?

The percentage yield formula is calculated to be the experimental yield divided by theoretical yield multiplied by 100. If the actual and theoretical yield ​is the same, the percent yield is 100%.

How do you calculate percent purity of aspirin?

So when I workout the percentage purity of my aspirin, it works out to be 106.8%. I use the formula: (actual moles/theoretical moles) X 100.
