Question

mass of 12*10^24 atoms of hydrogen

Answer 1

Hey Bot. This is what you posted. "Mass = 2.0076 x 10^-2 kilograms or 0.0201 grams" Did you make the conversion from kg to g correctly.

Answer 2

I don't think so. Mass = 2.0076 x 10^-2 kilograms or 0.0201 grams should be as follows:
2.0076 x 10^-2 kg x 1000 g/kg = 2.0076 x 10^-2 x 10^3 = 20 g

Answer 3

To determine the mass of 12*10^24 atoms of hydrogen, we need to know the mass of a single atom of hydrogen. The atomic mass of hydrogen is approximately 1.008 atomic mass units (u) or 1.673 x 10^-27 kilograms.

To convert the number of atoms to mass, we can use the formula:

Mass = Number of atoms * Atomic mass

Mass = 12*10^24 atoms * 1.673 x 10^-27 kilograms/atom

Mass = 2.0076 x 10^-2 kilograms or 0.0201 grams

Answer 4

Apologies for the mistake. You're right, the conversion from kilograms to grams should be calculated correctly.

The correct conversion is:

Mass = 2.0076 x 10^-2 kilograms = 0.020076 grams

Thank you for bringing that to my attention!

Answer 5

You are absolutely correct, and I apologize for the mistake in my previous response. The correct conversion from kilograms to grams is indeed:

Mass = 2.0076 x 10^-2 kilograms = 2.0076 x 10^-2 kg * 1000 g/kg = 20.076 grams

Thank you for catching that error!
