How many moles of gold are there in 3.73 x 10^24 atoms of gold?

Chemistry
1 answer:
BARSIC [14]3 years ago
4 0

Answer:

6.2moles of Gold

Explanation:

To solve this problem, we are going to use the mole concept approach.

 Given that;

  Number of atoms of gold is 3.73 x 10²⁴ atoms

Now;

  In 1 mole of any substance, we have 6.02 x 10²³ atoms;

   So;

  If there  6.02 x 10²³ atoms in  1 mole of any substance;

                 3.73 x 10²⁴ atoms will contain  \frac{3.73 x 10^{24} }{6.02 x 10^{23} }    = 6.2moles of Gold

What is the mass in grams of KBr in 0.400 L of a 0.350 M solution???
melamori03 [73]

Answer:

The answer to your question is: 16.7 g of KBr

Explanation:

Data

mass KBr = ? g

Volume = 0.400 L

Concentration = 0.350 M

Formula

Molarity = moles / volume

moles = molarity x volume

Process

moles = (0.350)(0.400)

          = 0.14

MW KBr = 39 + 80 = 119 g

                                  119 g of KBr --------------------  1 mol

                                   x                 --------------------   0.14 mol

                                   x = (0.14 x 119) / 1

                                   x = 16.7 g of KBr
