Question

What mass of sodium is contained in 54g Na2CO3

Answer 1

Answer:

Explanation:

G.M.U. of Sodium Carbonate = 23*2  +   12    +   16*3

                                                =   46 + 12+48

                                                =  106 grams

106g of sodium carbonate has 46g sodium

54g of sodium carbonate will have x grams

thus

x = 54 * 46/106

 = 23.4 grams
