Answer 1

The amount, in grams, of carbon tetrachloride that would be present, will be 22.99 grams.

Finding the mass from the number of particles

For every one mole of any substance, there are 6.022 x $10^{23}$ atoms of particles. This is according to Avogadro.

Now, there are 9 x $10^{22$ particles in this particular carbon tetrachloride.

If 1 mole = 6.022 x $10^{23}$ particles

Then,

9 x $10^{22$ particles =  9 x $10^{22$ x 1/6.022 x $10^{23}$ particles

                       = 0.1495 moles

Carbon tetrachloride has the chemical formula CCl4 and has a molar mass of 153.82 g/mol.

Recall that: mole = mass/molar mass

Hence, mass = mole x molar mass.

Mass of 0.1495 moles CCl4 = 0.1495 x 153.82 = 22.99 grams
