Answer:

The final answer is 60.

Explanation:

According to the original information given, the estimated average number of shoppers in the original store at any time (N) is 45. In the question, it states that, in the new store, the manager estimates that an average of 90 shoppers per hour (60 minutes) enter the store, which is equivalent to 1.5 shoppers per minute (r). The manager also estimates that each shopper stays in the store for an average of 12 minutes (T). Thus, by Little's law, there are, on average, N=rT=(1.5)(12)=18 shoppers in the new store at any time. This is

   \frac{45-18}{45}*100=60

percent less than the average number of shoppers in the original store at any time.

What is the weight percent of a caffeine solution made by dissolving 6.35 g of caffeine, C8H10N4O2, in 75 g of benzene, C6H6?
SCORPION-xisa [38]

The weight percent is of caffiene is 7.98%.

There are several ways of expressing concentration in chemistry. One of the methods of expressing concentration is by the use of percentage.

In this case, we want to obtain the percent weight/weight concentration of caffeine in benzene.

From the question, we can see that;

Mass of solute = 6.5 g

Mass of solvent = 75 g

percent w/w = mass of solute/ mass of solute + mass of solvent × 100/1

percent weight of caffeine=

6.5/6.5 + 75 × 100/1 =7.98%
