How many grams of ag2co3 are required to reacr with 28.5 ml of 1.00 m naoh solution?

The reaction between Ag2CO3 and NaOH is shown by the equation below 
Ag2CO3 + NaOH = Ag2O + Na2CO3 +H2O
we can determine the number of mole of sodium hydroxide 
by (2.85 ml × 1) ÷ 1000 ml , since according to molarity 1 mole is contained in 100ml. 
we get 0.00285 moles of NaOH
Using the mole ratio we can get the moles of Ag2CO3
Mole ratio: Ag2NO3 : NaOH  = 1:1 
Therefore, the moles of Ag2CO3 will be 0.00285 moles
but 1 mole of silver carbonate is equivalent to 275.8 g
Thus the mass will be calculated by 0.00285 moles × 275.8g = 0.78603g
Mass of silver carbonate required will be 0.78603g

It dont even matter because at the end of thre day we gone life like it ius s
