It will cost $21 to drive from Monroe to Boston.

<em>Step 1</em>. Convert <em>kilometres to miles </em>

Distance = 240 km × (1 mi/1.609 km) = 149.2 mi

<em>Step 2</em>. Calculate the <em>gallons of gas</em>

V = 149.2 mi × (1 gal/27 mi) = 5.52 gal

<em>Step 3</em>. Calculate the <em>cost of the gas</em>

Cost = 5.52 gal × ($3.75/1 gal) = <em>$21</em>

Write a balanced chemical equation that describes an acid-base reaction that would allow you to determine the moles of aspirin p
Kryger [21]

A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is

C_{9} H_{8}O_{4} + NaOH⇒ C_{9} H_{7}O_{4} Na+ H_{2} O

Aspirin, also known as acetylsalicylic acid, is a nonsteroidal anti-inflammatory drug used to reduce pain, fever, and/or inflammation, and as an antithrombotic.

Aspirin is a benzoic acid with an ortho-substituted acylated alcohol function (actually a phenol). Therefore, two reactions can occur when aspirin and NaOH are combined: In fact, several aspirin formulations contain this ingredient.

Hence, A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is

C_{9} H_{8}O_{4} + NaOH⇒ C_{9} H_{7}O_{4} Na+ H_{2} O
