Answer : The correct option is, (A) C_{6}H_{12}O_6

Explanation :

Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.  

Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

n=\frac{\text{molecular mass}}{\text{empirical mass}}

As we are given that the empirical formula of a compound is CH_2O and the molar mass of compound is, 180.2 gram/mol.

The empirical mass of CH_2O = 1(12) + 2(1) + 1(16) = 30 g/eq

n=\frac{\text{molecular mass}}{\text{empirical mass}}

n=\frac{180.2}{30}=6

Molecular formula = (CH_2O)_n=(CH_2O)_6=C_{6}H_{12}O_6

Thus, the molecular formula of the compound will be, C_{6}H_{12}O_6

A person walking covers 5.20 m in 10.4 s. How fast is the person moving?
salantis [7]

Answer:

<h2>0.50 m/s</h2><h2></h2>

Explanation:

Velocity = distance over time

where distance = 5.20 m

                   time = 10.4 s.

velocity = <u>  5.20  m </u>

                  10.4 s.

            = 0.50 m/s

You dissolve the sample of fd&amp;c red 40 (molar mass 496.4200 g/mol) in enough water to make 250.0 ml of solution. we call thi
icang [17]
Molar mass 496.4200 g/mol

Number of moles:

40 g x 1 mol / 496.4200 => 0.08057 moles

Volume in liters:

250.0 mL / 1000 => 0.25 L

Therefore:

M = moles / V

M = 0.08057 / 0.25

 = 0.32228 M

hope this helps!
