$\huge \sf {\orange {\underline {\pink{\underline {❥︎A᭄ɴsᴡᴇʀ࿐ :−}}}}}$

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams. 9. Formic acid. Its formula has twice as many oxygen atoms as the other two compounds (one each).

Answer 2

Mode refers to the value that occurs a most or the maximum number of times in a data series.

Mode formula

• Individual Series:

We find the mode of an individual series by simply inspecting it and finding the item that occurs maximum number of times.

• Discrete Series:

The Mode of a discrete series is the value of the item that has the highest frequency.

• Frequency Distribution or Continuous Series:

Firstly, we need to find out the Modal class. Modal class is the class with the highest frequency. Then we apply the following formula for calculating the mode:

$mode = 1 + h \frac{∱_{1} - ∱_{0} }{(2 ∱_{1} - ∱_{0} - ∱_{2}) }$
