1.6x10^23 lead atoms. Find the weight in grams
Ber [7]
Moles of lead(Pb) = 1.6x10^23/6.02x10^23 = 0.265 moles.

Weight of lead = moles x atomic weight of lead
                         =  0.265x207.2
                         =  54.908 grams.

Hope this helps!

Suppose a friend says that we don't need to worry about the rising temperatures associated with global climate change. Her claim
ludmilkaskok [199]

Answer:

Carbonic acid could be formed.

Explanation:

Hello,

Based on her claim, it would be a really useful strategy to prevent global warming, nevertheless, there would be a problem if a increasing amount of carbon dioxide is not buried at the bottom of the ocean yet it flows freely along the sea and probably reacting with the water, causing carbonic acid to be formed  and subsequently cutting back the sea's pH (increasing its acidity).

It would be useful, but a constant monitoring of the sea's pH must be needed because this could cause some species to be affected not only by the temperature but for the acid pH as well.

Best regards.

Their weights could be different.
Their volumes could be different. 
Their densities could be different.

The volume for an ounce of lead is much different than an ounce of aluminum.

the weight of a cubic meter of balsa wood is much different (and much lighter) than a cubic meter of water. That's why the ancients used balsa for their rafts.
