"how many grams of sucrose (c12h22o11) are in 1.55 l of 0.758 m sucrose solution"
Ierofanga [76]
<span>You would use the equation: Molarity M equals amount of solution over volume of solution. So, 0.758 M equals x L divided by 1.55 L OR 0.758 M = x L / 1.55 L . To solve: 1.55 multiplied by 0.758 equals 1.1479. The answer is 1.1479.</span>

How many electrons are needed in the outer energy levels of most atoms to be chemically stable?
Tatiana [17]
Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.
