By using the formula-
As 1 with 6 zeros, we convert it into exponential form.
As this above value is fraction type, we can do the reciprocal, thus, the exponent gets a negative value.
Now combine with given question.
4 moles of NaOH is present in the given 160 grams of NaOH.
<h3>How we calculate moles?</h3>
Moles of any substance will be calculated as:
n = W/M, where
W = given mass of NaOH = 160 grams (given)
M = molar mass of NaOH = 40 g/mole
Moles of NaOH is calculated as:
n = 160g / 40g/mol = 4 moles
Hence, moles of sodium hydroxide (NaOH) is 4 moles.

A general formula of an acid always start with an hydronium ion or H+. The general formula of an acid have to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic."
Answer:
Kelvin = Celsius + 273.15
Explanation:
Instead of 273.15 you can use just 273 as well
I'm dumb too, but oxygen is basically just plants.
you can't breathe without nature.
