CareaCu+2AgNO_(3)arrow Cu(NO_(3))_(2)-2Ag how many p games of copper ca complexely react with 120g of silver

To solve this problem, we need to use the balanced chemical equation and the given information to find the amount of copper that can completely react with 120g of silver.<br /><br />Given information:<br />- Balanced chemical equation: $Cu + 2AgNO_{3} \rightarrow Cu(NO_{3})_{2} + 2Ag$<br />- Mass of silver: 120g<br /><br />Step 1: Calculate the molar mass of silver (Ag).<br />Molar mass of Ag = 107.87 g/mol<br /><br />Step 2: Calculate the number of moles of silver.<br />Number of moles of Ag = Mass of Ag / Molar mass of Ag<br />Number of moles of Ag = 120g / 107.87 g/mol = 1.11 mol<br /><br />Step 3: Use the balanced chemical equation to find the number of moles of copper (Cu) that can completely react with 1.11 mol of silver.<br />According to the balanced equation, 1 mol of Cu can react with 2 mol of Ag.<br />Number of moles of Cu = Number of moles of Ag / 2<br />Number of moles of Cu = 1.11 mol / 2 = 0.555 mol<br /><br />Step 4: Calculate the mass of copper that can completely react with 120g of silver.<br />Mass of Cu = Number of moles of Cu × Molar mass of Cu<br />Mass of Cu = 0.555 mol × 63.55 g/mol = 35.3g<br /><br />Therefore, 35.3g of copper can completely react with 120g of silver.
