Answer:
C9H13N
Explanation:
Since there is no common factor besides 1, the formula is already the empirical formula for this compound.
Answer:
false
Explanation:
water has 2 hydrogen molecules and 1 oxygen molecule. hint:H20
Answer:
Gas
Explanation:
Its particles have the most kinetic energy.
the Empirical formula of the compound is calculated as follows
find the moles of each element
moles = mass/molar mass
that is Magnesium= 0.564 g /24 g/mol = 0.0235 moles
For oxygen = 0.376 g /16 g/mol= 0.0235 moles
find the mole ratio by dividing both moles of by 0.0235 moles
magnesium = 0.0235/0.0235= 1mole
oxygen= 0.0235 /0.0235= 1mole
therefore the empirical formula = MgO
