Answer:
Check the explanation
Explanation:
When there are two molecules then these molecules are described as stereoisomers if they are comprised of the same atoms associated in the same sequence, but the atoms are situated differently in the space. The disparity between stereoisomers can only be observed when the molecules is considered in a three-dimensional arrangement.

Telephones began as large, clunky devices capable of transmitting and receiving voice messages over short distances, then evolved to lighter, transportable cellular devices capable of enabling communications over large distances. In the United States, Alexander Graham Bell receives credit for producing the first telephone in 1876. Bell established a basic system of communications allowing people to talk with each other remotely over short distances through receivers. <span>As with other technologies, phone technologies improved dramatically and rapidly following Bell's introduction of the telephone to American life. In addition to improvements in the device itself, transmissions methods improved as well. By 1900, telephone companies established communication lines through many American cities, allowing people to connect over larger distances. These lines contained special coils to reduce static and expedite transmissions. Telephone calls remained limited to local regions within the borders of the United States through 1915. Then, Alexander Graham Bell completed the first transcontinental call with Thomas Watson. Rotary phones emerged just before 1920, and a numbering plan arrived in the late 1940s to allow fast and direct connections between callers. In 1956, telephone cables permitted transcontinental calls for the first time. In the 1960s and 1970s, phone use extended to emergency service and the military. Portable phones arrived in the early 1970s; by 2000, thousands of Americans carried lightweight, compact phones wherever they went. AND THEY HAVE IPHONES NOW XDD

Answer:
51.859 grams
Explanation:
Given:
Mass of sugar in the crunch cereal per serving= 11.0 grams
Mass of cereal served per serving = 60.0 grams
Molar mass of the sugar (C₁₂H₂₂O₁₁) = ( 12 × 12 + 22 × 1 + 16 × 11 ) = 342 grams
Number of moles of sugar per serving = Mass / Molar mass
= 11.0 / 342
= 0.03216 moles
Now,
0.03216 moles sugar requires 60 grams cereal
for 0.0278 moles of sugar, cereal required = (60 / 0.03216) × 0.0278
or
for 0.0278 moles of sugar, cereal required = 51.859 grams
