How many grams of dofium can react in 250. mL of 3.00 M HCl<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n To determine how many grams of dofium<\/strong> can react with 250. mL of 3.00 M HCl<\/strong>, we must know the balanced chemical equation<\/strong> for the reaction between dofium<\/strong> and HCl<\/strong>.<\/p>\n\n\n\n Let\u2019s assume that dofium (Df)<\/strong> reacts with hydrochloric acid (HCl) in a 1:2 mole ratio \u2014 similar to how some metals (like magnesium) react with hydrochloric acid: Df (s)+2HCl (aq)\u2192DfCl2(aq)+H2(g)\\text{Df (s)} + 2 \\text{HCl (aq)} \\rightarrow \\text{DfCl}_2 \\text{(aq)} + \\text{H}_2 \\text{(g)}<\/p>\n\n\n\n Given:<\/p>\n\n\n\n Moles of HCl=M\u00d7V=3.00\u2009mol\/L\u00d70.250\u2009L=0.750\u2009mol\\text{Moles of HCl} = M \\times V = 3.00 \\, \\text{mol\/L} \\times 0.250 \\, \\text{L} = 0.750 \\, \\text{mol}<\/p>\n\n\n\n From the balanced equation, 1 mole of Df reacts with 2 moles of HCl<\/strong>. Moles of Df=0.7502=0.375\u2009mol\\text{Moles of Df} = \\frac{0.750}{2} = 0.375 \\, \\text{mol}<\/p>\n\n\n\n To find grams, we need the molar mass of dofium<\/strong>. If dofium is a fictional element<\/strong>, we can assign it a hypothetical molar mass. Let’s assume dofium has a molar mass of 200. g\/mol<\/strong> (for calculation purposes). Mass=moles\u00d7molar mass=0.375\u00d7200=75.0\u2009g\\text{Mass} = \\text{moles} \\times \\text{molar mass} = 0.375 \\times 200 = 75.0 \\, \\text{g}<\/p>\n\n\n\n 75.0 grams of dofium<\/strong> can react with 250. mL of 3.00 M HCl.<\/p>\n\n\n\n To determine how much of a substance (in grams) can react with an acid like HCl, we start by calculating the number of moles<\/strong> of HCl present using the formula: Moles=Molarity\u00d7Volume\\text{Moles} = \\text{Molarity} \\times \\text{Volume}<\/p>\n\n\n\n Molarity tells us how many moles of solute (in this case, HCl) are present per liter of solution. Since 250. mL is 0.250 L, we multiply 3.00 mol\/L by 0.250 L to get 0.750 moles of HCl.<\/p>\n\n\n\n Next, we need to understand how the dofium reacts. If it reacts like a typical Group 2 metal (e.g., Mg), one mole of dofium would react with two moles of HCl, forming a salt (dofium chloride) and hydrogen gas. Using the mole ratio from the balanced equation<\/strong>, we find that 0.750 moles of HCl would react with 0.375 moles of dofium.<\/p>\n\n\n\n Now, to convert moles to grams, we multiply by the molar mass. Since dofium is fictional, we estimate a reasonable molar mass\u2014200 g\/mol. Multiplying 0.375 moles by 200 g\/mol gives 75.0 grams.<\/p>\n\n\n\n This step-by-step process\u2014calculating moles from molarity and volume, applying mole ratios from the chemical equation, and converting moles to grams\u2014is fundamental in stoichiometry, helping chemists predict the quantities of substances involved in reactions.<\/p>\n","protected":false},"excerpt":{"rendered":" How many grams of dofium can react in 250. mL of 3.00 M HCl The correct answer and explanation is: To determine how many grams of dofium can react with 250. mL of 3.00 M HCl, we must know the balanced chemical equation for the reaction between dofium and HCl.
