One mole of molecules =
One mole of HCl Hydrochloric acid = 36.5 grams
1 H = 1 xx 1.00 gram/mole = 1.00 grams
1 Cl = 1 xx 35.45 grams/mole = 35.5 grams ( to 3 sig numbers)
1.00 + 35.5 = 36.5 grams/ moles

Which option contains a $2*g$ mass of sodium atoms....
$1.$ $5.24xx10^22*"sodium atoms?"$
$2.$ $6.022xx10^24*"sodium atoms?"$
$3.$ $3.12xx10^23*"sodium atoms?"$
$4.$ $5.24xx10^22*"sodium atoms?"$
We know that $1*mol$ contains $6.022xx10^23$ individual sodium atoms, and has a mass of $22.99*g$. And thus for $1.$ there is a $2*g$ mass of $Na$. For $2.$ there is...

A mass of $"18 g"$ of a compound $"M"_2"CO"_3 * x"H"_2"O"$ $(M_ "M metal" = "24 g/mol")$ is dissolved in $"500 mL"$ of water and titrated against a $"0.5-M"$ $"HCl"$ solution. If the volume of $"HCl"$ consumed is $"500 mL"$, the value of $x$ is?
The idea here is that you can use the number of moles of anhydrous metal carbonate that took place in the reaction to figure out the number of moles of...

One reaction that produces hydrogen gas can represented by the following unbalanced chemical equation: $Mg(s) + HCl(aq) -> MgCl_2(aq) + H_2(g)$. What mass of HCl is consumed by the reaction of 2.50 moles of magnesium?
$Mg(s) + 2HCl(aq) rarr MgCl_2(aq) + H_2(g)uarr$ And, given $2.5*mol$ metal (and stoichiometric acid), CLEARLY, there are $5.0*mol$ $HCl$ consumed......... And thus mass of $HCl=5.0*molxx36.46*g=182.3*g$.

If 5.00g of MnO2 reacts w/ 25.0mL of 6M HCL calculate the mass of Cl2 produced? I figured out MnO2 but stuck with HCl. I did 25mL HCl x(0.001L/1mL)x (6mol HCl/1 L) but I don't know where I should go now?
This reaction will produce $"2.63 g"$ of $Cl_2$ gas. Start with the balanced chemical equation, that is a must for any problem. $MnO_(2(s)) + 4HCl_((aq)) -> Cl_(2(g)) +...

(a) What is the molar concentration of a concentrated solution that contains 36.00 % $"HCl"$ by mass and has a density of $"1.24 g/dm"^3"$. (b) How you would prepare $"1.00 dm"3$ of 0.125 mol/L $"HCl"$ from the concentrated solution?
The correct of concentrated hydrochloric acid is $"1.19 g/cm"^3$. Step 1. Calculate the molar concentration of the conc. $"HCl"$ Assume that you have $"1 dm"^3$ of the concentrated acid. $"Mass...

What volume of concentrated $HCl$ contains a mass of $125*g$ $HCl$?
The conc. acid you use in a lab is $34%$ $w/w$. As a I recall, this has a of approx. $1.17*g*mL^-1$. We require $125*g*HCl$ $=$ $(125*g)/(36.46*g*mol^-1)$ $=$ $3.43*mol$. For volume,...

Commercially available concentrated Hcl contains 38% Hcl by mass. (1) what is the molarity of the solution ( density of solution =1.19 g mL -1)?
(2) What volume of concentrated Hcl is required is required to make 1.0 L of an 0.10 M Hcl?
Question 1: $HCl(38%) = ((38 g HCl)/(100g"Soln")) = ((?"moles""HCl")/(1.0 "Liter""Solution"))$ => Moles of HCl in 38 grams = $((38 g HCl)/(36(g/"mol")))=1.06 "mole"HCl$ => Volume of Solution (Liters) containing 1.06 mole...

An aqueous stock solution is $36.0%$ HCl by mass and its density is $"1.18 g/mL"$. What volume of this solution is required to make $"1.00 L"$ of $"1.75 mol/L"$ $"HCl"_((aq))$? Give your answer in millilitres, accurate to three significant figures.
As you know, a $"1.75-mol L"^(-1)$ hydrochloric acid solution will contain $1.75$ moles of hydrochloric acid, the , for every $"1 L"$ of solution. So right from the start, you...

A solution of HCl in water has a density of 1.1 g/mL. What is the mass% of HCl in the solution if 150 mL of the solution contains 30. g of HCl?
The first thing that you need to do here is to use the of the solution to determine the mass of $"150 mL"$ of this hydrochloric acid solution....

50.0 mL of 0.100 M $"NH"_3$ is titrated with 0.100 M $"HCl"$. What is the pH of the $"NH"_3$/$"HCl"$ mixture after the addition of 25.0 mL of $"HCl"$?
After reading this, take the time to compare this answer with . It is very important that you see these are the same situation with the roles reversed... Spotting patterns...
