Answer: , 0.533 L
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
According to avogadro's law, 1 mole of every substance occupies 22.4 L of volume at STP.
Number of moles =
moles of calcium carbonate =
As 1 mole of calcium carbonate produces = 22.4 L of carbon dioxide at STP
Thus 0.0238 moles of calcium carbonate produces = of carbon dioxide at STP
Answer:
is the density of solid calcium.
Explanation:
Formula used :
where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
We have:
r = 197 pm =
M = 40 g/mol
Z = 4
On substituting all the given values , we will get the value of 'a'.
is the density of solid calcium.
