\\ \tt\rightarrowtail Molarity=\dfrac{Mass}{Molar\:mass\times Volume}

\\ \tt\rightarrowtail Volume=\dfrac{Molarity(Molar\:mass)}{Mass}

\\ \tt\rightarrowtail Volume=\dfrac{0.2(58.5)}{30.2}

\\ \tt\rightarrowtail Volume=0.387L

  • Volume=387mL

Answer choices for the above question

Quesiton 5 says

Which of these inferences about the author’s point of view is best supported by the entire excerpt?

A. “She’s simply called HeLa, the code name given to the world’s first immortal human cells—her cells, cut from her cervix just months before she died.”

B. “I’ve spent years staring at that photo, wondering what kind of life she led, what happened to her children, and what she’d think about cells from her cervix living on forever—bought, sold, packaged, and shipped by the trillions to laboratories around the world.”

C. “One scientist estimates that if you could pile all HeLa cells ever grown onto a scale, they’d weigh more than 50 million metric tons—an inconceivable number, given that an individual cell weighs almost nothing.”

D. “All of the stories mentioned that scientists had begun doing research on Henrietta’s children, but the Lackses didn’t seem to know what that research was

Which process releases energy that eventually produces lightning in the thunderstorm?
Ira Lisetskai [31]

Answer:

Answer: B. Water condenses to form clouds.

Explanation:

When the moisture condenses, this results in the release of energy. The energy causes the air to be warm and results in the rise of air in the upper atmosphere. This process results in the instability in the atmosphere and cumulonimbus clouds are formed. These clouds support lightening during a thunderstorm.
