Answer:
92.2 m
Explanation:
Given that:=
The breadth = 304 mm
Height = 0.014 mm
Let Length = x mm
Volume = 
Thus,
Volume = 
Also, 1 mm³ = 0.001 cm³
So, volume = 0.004256 cm³
Given that density = 2.7 g/cm³
Mass = 1.06 kg = 1060 g
So,

So,
0.004256*x = 392.59
x = 92243.89 mm
Length of foil = 92243.89 mm = 92.2 m

Answer: -
2.5 moles of calcium atoms are in 2.5 moles of calcium carbonate CaCO₃
Explanation: -
In order to solve such types of problems, the first step would be to write the chemical formula of the compound.
The chemical formula of calcium carbonate = CaCO₃
The chemical symbol of Calcium is Ca.
From the formula of calcium carbonate we can see that
1 mole of CaCO₃ has 1 mole of Ca
2.5 mole of CaCO₃ has 
= 2.5 mol of Ca.
∴2.5 moles of calcium atoms are in 2.5 moles of calcium carbonate CaCO₃
