A 60.2-ml sample of hg (density = 13.6 g/ml) contains how many atoms of hg?
Over [174]
Density is calculated using the following rule:
density = mass / volume
therefore:
mass = density * volume
mass of Hg = 13.6 * 60.2 = 818.72 grams

From the periodic table:
molar mass of Hg = 200.59 grams

number of moles = mass / molar mass
number of moles of Hg = 818.72 / 200.59 = 4.08 moles

each mole contains Avogadro's number of atoms.
Therefore,
number of atoms in the given sample = 4.08 * 6.022 * 10^23
                                                            = 2.456976 * 10^24 atoms

6CO2 + 6H20 → C,H120, + 602
tatyana61 [14]

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 6O2

How many molecules of CO2 are present?

6 moles

How many atoms of oxygen are present in the reactants?

(6 * 2) + (6 * 1 ) = 12 + 6 = 18

How many atoms of carbon are present in the products?

(6 * 1 ) = 6

How many total atoms are present in C6H12O6?

6 + 12 + 6 = 24 atoms

Is the equation above balanced or unbalanced?

This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.
