Answer:
precipitate means I think so mass of agcl ask after reaction which is formed that is 7gram
Explanation:
first we will write the chemical equation
agno3+nacl= agcl + nano3
170g. 58.5g. 143.5g
16.9%of agno3 means 16.9g I'm 100ml solution in 50ml of solution=8.45 g
like same 5.8%of nacl means =2.9g in 50ml solution
all reactants and product are in 1 mol
mol of agno3=8.45/170=0.049
mol of nacl= 2.9/58.5=0.049
abhi yha pe sabke to 1mol form ho rhe hai
therefore mass of agcl=no of mol×molar mass
=0.049×143.5=7
mass precipitate=7g
if there is any mistake then lam sorry
