Two moles of MgsO4•7H2O contain ___ grams of MgSO4•7H2O

492.6g

Explanation:

Given parameters:

Number of moles of MgSO₄.7H₂O = 2moles

Unknown:

Mass = ?

Solution:

To find the mass of this compound;

       Mass  = number of moles x molar mass

Molar mass of MgSO₄.7H₂O = 24.3 + 32 + 4(16) + 7[2(1) + 16]

                                                = 246.3g/mol

Mass  = 2 x 246.3 = 492.6g

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
