A typical aspirin tablet contains 5.00 grains of pure aspirin analgesic compound. The rest of the tablet is

Pavel [41]

Answer:

$Tablets=193$

Explanation:

Hello,

In this case, given that a typical aspirin tablet contains 5.00 grains of pure aspirin, the first step here is to compute the mass of those grans per tablet given that 1.00 g = 15.4 grains:

$m=5.00grains*\frac{1.00g}{15.4grains}=0.325g$

In such a way, the number of aspirin tablets are computed considering the total mass of aspirin and the mass per tablet:

$Tablets=\frac{62.7g}{0.325g}\\ \\Tablets=193$

Best regards.

Which pair of reactants will undergo aldol condensation to produce methylvinyl ketone?

xenn [34]

When formaldehyde and acetone then react with each other( aldol condensation) then it will be formed methyl vinyl ketone.

In organic chemistry, an aldol condensation would be a condensation reaction in which an enol and enolate ion combines with a carbonyl chemical to produce a -hydroxy aldehyde or -hydroxy ketone, that is then dehydrated to produce a conjugated enone.

In aldol condensation, when formaldehyde and acetone then react with each other then it will be formed methyl vinyl ketone.

It can be written as

$CH_{2} O + CH_{3} COCH_{3}$ → $HOCH_{2} -CH_{2} -CO-CH_{3}$
