Answer:

the empirical formula gives the simplest ratio of whole numbers of components in the compound. Molecular formula gives the actual composition of elements in the compound.

Explanation:

empirical formula - CH₂O

Mass of one empirical unit = 12 + (1x2) + 16 = 30 a.m.u

We have to next calculate how many empirical units make up the molecular formula. For that we have to divide molecular mass by mass of one empirical unit.

Number of empirical units = 180 a.m.u / 30 = 6

There are 6 empirical units 

Therefore molecular formula = 6 x(CH₂O) = C₆H₁₂O₆

Molecular formula = C₆H₁₂O₆

elixir [45]
For the first question:
Valuable ore deposits and gem crystals are often associated with igneous intrusions. So for this question the correct option is option “d”. An example like the Pegmatite’s, which are a form of igneous intrusions, is responsible for the creation of variety of gems like topaz and tourmaline.
For the second question:
For this specific question, option “c” seems to be the correct option. Weathering, deposition, compaction, cementation are the possible sequence that leads to the formation of sedimentary rocks.

How many magnesium atoms are contained in 3.75 moles of magnesium?
Katarina [22]
In 1 mole of magnesium there are Avogadro's number of atoms are present.
Avogadro's number = 6.023 x 10²³ 
1 mole = 6.023 x 10²³ atoms
3.75 moles = 3.75 x 6.023 x 10²³ 
=2.26 x 10²⁴
So, in 3.75 moles of magnesium there are 2.26 x 10²⁴ atoms of magnesium are present.
