A sample of groundwater is tested for arsenic by reacting it with excess silver nitrate until no more solid product is formed as per the reaction below. If {x} grams of silver arsenate is obtained, how many grams of sodium arsenate were in the groundwater sample? The molar mass of Ag3AsO4is 462.52 g/mol. The molar mass of Na3AsO4 is 207.9 g/mol. Na3AsO4(aq)+AgNO3(aq)→3NaNO3(aq)+Ag3AsO4(s)

{x} mL of {y} M NaOH is required to titrate {z} mL of an unknown concentration of HCl. What is the molarity of the HCl solution?

{x} grams of Yr2 and 2.500 grams of X react according to the unbalanced reaction below. Calculate the percent yield if {y} grams of YrX3 is collected. The molar mass of Yr2 is 45.656 g/mol, the molar mass of X is  95.416 g/mol, and the molar mass of YrX3 is 309.076 g/mol. Yr2 + X →YrX3

Gt3 and Ly react according to the unbalanced reaction to form the compound GtLy{y}. Calculate how many grams of GtLy{y} form from {x} grams of Ly when reacted with excess Gt. The molar mass of Ly is {z} g/mol and the molar mass of GtLy{y}is {a} g/mol.

Gt and Ly react according to the unbalanced reaction below. First, balance the reaction and then calculate how many moles of GtLy{y} form from {x} moles of Ly when reacted with excess Gt2 Gt2 + Ly →GtLy{y}
