Determine the mass of sodium chloride that will react completely with $23\mathrm{.}9g$ of silver nitrate. $]$

A student wrote the following observations in an experiment where a copper metal strip was placed in a solution of silver chlorate.

initial mass $of$ copper $=1\mathrm{.}78g$

final mass $of$ copper $=0\mathrm{.}89g$

Calculate the amount of silver that would has formed during the experiment. $[3\mathrm{.}0g]$

$3.$ If $13\mathrm{.}89g$ of zinc react completely with phosphoric acid, what mass of zinc phosphate will result? $[27\mathrm{.}34g]$

$4.$ What mass of sodium metal will react with water to produce $31\mathrm{.}4g$ of hydrogen gas? $,715g]$

$5.$ What mass of sodium hydroxide will result from the reaction of $59\mathrm{.}8g$ of barium hydroxide with sodium carbonate?

$[27\mathrm{.}9$ g $]$

$6.$ Using the reaction given, what mass of sodium hydrogen carbonate would react with $1\mathrm{.}27kg$ of aluminium sulphate? Please note you will first need to balance this reaction.
