Scientific notation<span> refers to a mathematical expression that is used to represent a decimal number between 1 and 10 multiplied by ten, or we can say that to write a large numbers using less digits.
Diameter of chlorine atom = </span><span>175 picometers (pm)
</span>175 pm = <span>0.000000000175 m
in scientific notation we will write </span>0.000000000175 m as <span>1.75 x 10</span>¹⁰ m
It's essentially another word for concentration, of the acid. e.g. "the molarity of the acid is 3moldm^-3"
