Answer:
16 moles
Explanation:
from the equation:
4Fe + 3O2 -----> Fe2O3
the mole ratio of Fe to O2 follows,
3 moles O2 reacts with 4 moles Fe.
therefore,
1 mole O2 reacts with 4/3 moles Fe
and 12 moles O2 reacts with (4/3) × 12 moles Fe = 16 moles
The number of protons and the number of neutrons determine an element's mass number: mass number
Answer:
48.03grams
Explanation:
Density of a substance is calculated as follows:
Density (g/cm³) = mass (g) / volume (cm³)
Based on the information given in this particular question:
Density of lead (Pb) = 11.3 g/cm³
Volume of lead (Pb) = 4.25 cm³
Density = m/V
11.3 = mass/4.25
Mass = 48.025
= 48.03grams.
