How many grams of fluorine are needed to react with 8.5g of phosphorus?
love history [14]

Step 1: write the equation:

                                          P₄(s) + 6F₂(g) → 4PF₃(g) 


Step 2: Molar mass of P₄ = 30.97 g/mol × 4 = 123.88 g/mol


Step 3: Number of moles of phosphorus

                                                    n = m/M 

                                                    n = 8.5 g/123.88g/mol

                                                    n = 0.07 moles


Step 4: 0.07 × 12 = 0.84 moles of fluorine.

Fluorine is diatomic gas so we multiplied the number of moles by 12.


Step 5: To find the mass of fluorine we multiply the number of moles with the molar mass.

                            Mass of fluorine = 0.84 ×  228 

                                                        = 191.52 grams.

How many atom of oxygen are in 2mole of O2​
GenaCL600 [577]

Answer:

12.044  × 10²³ atoms of oxygen

Explanation:

Given data:

Number of atoms of oxygen = ?

Moles of oxygen = 2 mol

Solution:

Avogadro number:

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms of oxygen

2 mole × 6.022 × 10²³ atoms of oxygen / 1 mole

12.044  × 10²³ atoms of oxygen

Isotopes are atoms with the same number of protons, but different numbers of neutrons.

Explanation:

Ex.

Ne 20/10

Ne 21/10

Ne 22/10

*the number of protons in an atom must stay the same or the element itself will change drastically
