PLEASE HELP WITH ALL! Do the following Mole conversions:

The answer to your question is below

Explanation:

1)  number of molecules = x

   23 g of CoCl₂

Molar mass CoCl₂ = 59 + 71 = 130 g

                    130 g 6.023 x 10²³ molecules

                      23 g  x

                      x = (23 x 6.023 x 10²³) / 130

                     x = 1.066 x 10²³ molecules

2)

3.2 moles of H₃PO₄ to grams

Molar mass = 3 + 31 + (16 x 4)

                   = 98 g

                      98 g 1 mol

                        x     3.2 moles

                        x = (3.2 x 98)/1

                        x = 313.6 g

3)

2.2 moles of (NH₄)₂ to grams

Molar mass = (14 x 2) + (8 x 1)

                    = 36 g

                      36 g of (NH₄)₂ 1 mol

                        x                     2.2 moles

                        x = (2.2 x 36)/1

                        x = 79.2 grams

4)

Molecules = ? 4.5 g of NH₄SO₂

Molar mass = 14 + 32 + 32 + 4

                   = 82 g

                      82 g of NH₄SO₂ 6.023 x 10²³ molecules

                      4.5 g                   x

                      x = (4.5 x 6.023 x 10²³) / 82

                      x = 3.3 x 10²³ molecules

5)

Liters of N₂ = ?  7.9 x 10³⁰ particles

                     22.4 l 6.023 x 10²³ particles

                        x        7.9 x 10³⁰

                        x = (7.9 x 10³⁰ x 22.4) / 6.023 x 10²³

                        x = 2.93 x 10⁸ particles

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
