A barometer is a tool, not a variable. A barometer measures barometric or air pressure, which is a variable that meteorologists use to predict the weather.

The tiara worn by Kate Middleton for her wedding to Prince William of England contains 888 diamonds and belongs to the British m
allsm [11]

Answer:

The number of atoms in the gemstones of that tiara is 8.9125\times 10^{24} atoms.

Explanation:

Number of diamonds ion tiara = 888

Mass of  each diamond = 1.0 carat = 0.200 g (given)

Mass of 888 diamonds in tiara:

888\times 0.200 g=177.600 g

Given that diamond is a form of carbon.

Atomic mass of  carbon atom = 12 g/mol

Moles of 77.600 g of carbon =\frac{177.600 g}{12 g/mol}=14.800 mol

Number of atoms of carbon 14.800 moles:

14.800 mol\times 6.022\times 10^{23} atoms =8.9125\times 10^{24} atoms

The number of atoms in the gemstones of that tiara is 8.9125\times 10^{24} atoms.
