Question

calculate mass of 12 gram mole of Na2CO3​

Answer 1

Answer:

Explanation:

I guess Q is little bit wrong because you are saying 12g is  the mass on na2co3 and then you are asking mass of na2co3

I guess Q should be like this :

calculate mass of 12 mole of Na2CO3.

so 1 mole of Na​₂O₃ have mass = 2(Na mass) + (C mass) + 3(O mass)

                                                   = 2(23) + 12 + 3 (16)

                                                    = 46+ 12 + 48

                                                    = 106g

  10 mole of it will weigh  

                                         = 106 * 10

                                         = 1060g

Answer 2

Answer:

1272g

Explanation:

12 gram mole means 12 moles

mass of 1 mole of Na2CO3​=106

mass of 12 gram mole of Na2CO3​ = 12*106

                                                         => 1272g
