How many moles of gold are equivalent to 1.204 × 1024 atoms?
LUCKY_DIMON [66]

Explanation:

It is known that the value of Avogadro's number is 6.022 \times 10^{23}.

Therefore, calculate moles of gold atoms as follows.

    Moles of gold atom = \frac{given number of atoms}{Avogadro's number}

                                    = \frac{1.204 \times 10^{24}}{6.022 \times 10^{23}mol^{-1}}

                                    = 0.199 \times 10 mol

                                    = 1.99 mol

Thus, we can conclude that 1.99 mol of gold atoms are equivalent to 1.204 \times 10^{24} atoms.

How many grams does f Cacl2 should be dissolved in 750.0 mL of water to make a 0.100 M solution Cacl2
AVprozaik [17]

Answer:

8.324 g

Explanation:

First we <u>convert 750.0 mL into L</u>:

  • 750.0 mL / 1000 = 0.750 L

Then we <u>calculate the required number of moles of CaCl₂</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • Molarity * liters = moles
  • 0.100 M * 0.750 L = 0.075 mol

Finally we <u>convert 0.075 moles of CaCl₂ into grams</u>, using its <em>molar mass</em>:

  • 0.075 mol * 110.98 g/mol = 8.324 g
