A student added three volumes: 0.351 ml, 0.350 ml and 0.349 ml. The total volume should be reported (type the units too) as:

Lostsunrise [7]

Answer:- 1.050 mL

Solution:- Volume is an additive property. So, we add all the three given volumes to get the total volume.

Total volume = $0.351mL+0.350mL+0.349mL=1.050mL$

Since in addition, we go with least decimal places, the answer must have three decimal places as all the given numbers have three decimal places each.

Hence, the total volume should be reported as 1.050 mL.

How many grams of Aspirin (acetylsalicylic acid) should we form in this reaction if we started with 2.08g of Salicyclic Acid?

Kamila [148]

Taking into account the reaction stoichiometry, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

C₄H₆O₃ + C₇H₆O₃ (Salicyclic Acid) →C₉H₈O₄ (aspirin) + C₂H₄O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

C₄H₆O₃: 1 mole
C₇H₆O₃: 1 mole
C₉H₈O₄: 1 mole
C₂H₄O₂: 1 mole

The molar mass of the compounds is:

C₄H₆O₃: 102 g/mole
C₇H₆O₃: 138 g/mole
C₉H₈O₄: 180 g/mole
C₂H₄O₂: 60 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

C₄H₆O₃: 1 mole ×102 g/mole= 102 grams
C₇H₆O₃: 1 mole ×138 g/mole= 138 grams
C₉H₈O₄: 1 mole ×180 g/mole= 180 grams
C₂H₄O₂: 1 mole ×60 g/mole= 60 grams

<h3>Mass of aspirin formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 138 grams of salicyclic acid form 180 grams of aspirin, 2.08 grams of salicyclic acid form how much mass of aspirin?

$mass of aspirin=\frac{2.08 grams of salicyclic acidx 180 grams of aspirin}{138 grams of salicyclic acid}$
