To contain the same number of atoms also mean to contain the same number of moles. So let us say that X is the mass of Silver Ag required, so that:

X / 107.87 = 10 / 10.81

<span>X = 99.79 g</span>

<u>Answer:</u> The mass of silver atoms is 99.78 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}      .....(1)

<u>For boron:</u>

Given mass of boron = 10.0 g

Molar mass of boron = 10.81 g/mol

Putting values in equation 1, we get:

\text{Moles of boron}=\frac{10.0g}{10.81g/mol}=0.925mol

As, the number of atoms of silver are same as the number of atoms of boron. This means that number of moles of boron will be same as number of moles of silver.

Now, calculating the mass of silver atoms by using equation 1, we get:

Molar mass of silver = 107.87 g/mol

Moles of silver = 0.925 moles

Putting values in equation 1, we get:

0.925mol=\frac{\text{Mass of silver}}{107.87g/mol}\\\\\text{Mass of silver}=99.78g

Hence, the mass of silver atoms is 99.78 grams.

Can we cover the earth with one mole of pennies? Explain.
mezya [45]

Answer:

No we can’t cover the earth with one mole of pennies

Explanation:

We can’t cover the earth with one mole of pennies due to the fact that making this possible will require the flattening and extra expansion before it covers the whole surface.

The extra expansion and flattening with result in the loss of intermolecular forces and won’t remain as a solid and form other states of matter which won’t be able to cover the surface.
