Option B.
Current atomic models show the positive charged particles (protons) concentrated in the center (nucleus) of the atom, along with the neutrons, and the negative charged particles (electrons) distributed around (far from) the nucleus.
Answer:
100g/cm^3
Explanation:
density=mass/volume
convert mass in kg to g
1kg=1000g
5kg=5000g
therefore, density=5000g/50cm^3
=100g/cm^3
Do u know how to do phyrosus thearom?
Answer:
1.80 × 10²⁴ Molecules of Sucrose
Solution:
Number of Moles and Number of Particles (molecules in given case) are related to each other as,
Moles = Number of Molecules ÷ 6.022 × 10²³
Solving for Number of Molecules,
Number of Molecules = Moles × 6.022 × 10²³
Data Given;
Moles = 3 moles
Putting values in eq,
Number of Molecules = 3 mol × 6.022 × 10²³
Number of Molecules = 1.80 × 10²⁴ Molecules
