How many moles of mgci2 are there in 310 g of the compound? this question is not multiple choice. i have two blank boxes to put my answer in, one that says answer and the other one is labeled units.

Number of Moles are calculate by using following formula,

                                        Moles  =  Mass / M.mass     --- (1)

M.mass is calculated by adding the atomic masses of all elements present in molecule, Since, MgCl₂ contains one Mg (atomic mass = 24.3 g/mol) and two Cl atoms (atomic mass = 35.45 × 2 = 70.9 g/mol), So,

                            Molar mass = 24.3 g/mol  +  70.9 g/mol

                            Molar Mass of MgCl₂ = 95.2 g/mol

Now, putting values in eq. 1,

                                        Moles  = 310 g ÷ 95.2 g/mol

                                        Moles  = 3.256 moles

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
