The radius of an aluminum atom is 1.43 × 10−10 m. Calculate how many aluminum atoms are present in 1.00 cm3 of aluminum if all aluminum atoms are perfectly aligned in all three dimensions. hi everyone. i got this exercise in a chemistry class and would like to hear how you would go about solving it.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.

Suppose that a certain fortunate person has a net worth of $71.0 billion ($7.10×1010). if her stock has a good year and gains $3.20 billion (3.20×109) in value, what is her new net worth?
