Answer:
there is only 2 oxygen's in NaO2
Explanation:
Na O2
To solve for the new water level, let us first calculate
for the volume of the copper cylinder. The formula we can use is:
V = m / ρ
where V is the volume, m is the mass of the copper and ρ
is the density, therefore:
V = 48.85 g / (8.96 g / cm^3)
V = 5.45 cm^3
since cm^3 = mL
V = 5.45 mL
The new water level will be the initial volume of the
graduated cylinder plus the volume of the copper cylinder, therefore:
new water level = 20 mL + 5.45 mL
new water level = 25.45 mL
your answer is c) lead. because a leaded stained glass was used with lead glass which holded the pieces together.
