How many moles of potassium nitrate are produced when two miles of potassium phosphate react with two moles of aluminum nitrate?
First write balanced chemical equation for this ion-exchange reaction : $K_3PO_4+Al(NO_3)_3->3KNO_3+AlPO_4$. This balanced chemical equation represents ratio in which the chemicals combine and form products. So clearly 1 mole of...

How many moles of iron (lll) nitrate are in 200 grams of iron (Ill) nitrate?
$n = (200*g)/(241.86*g*mol^-1)$ $~=$ $0.80*mol$ $Fe(NO_3)_3$. How many moles of $O$, and $N$ does the given mass represent?

How many nitrate ions, NO3-, and how many oxygen atoms are present in 1.00 microgram of magnesium nitrate, Mg (NO3)2? Also what mass of oxygen is present in 1.00 microgram of magnesium nitrate?
Number of nitrate ions $"Moles of Mg"("NO"_3)_2 = 1.00 × 10^"-6" color(red)(cancel(color(black)("g Mg"("NO"_3)_2))) × ("1 mol Mg"("NO"_3)_2)/(148.31 color(red)(cancel(color(black)("g Mg"("NO"_3)_2)))) = 6.743 × 10^"-9"color(white)(l) "mol Mg"("NO"_3)_2$ $"Moles of NO"_3^"-" = 6.743...

Recall that liquid sodium reacts with chlorine gas to produce sodium chloride. You want to produce 581 g of sodium chloride. How many grams of sodium are needed?
$"Moles of sodium chloride"$ $(581*cancelg)/(58.44*cancelg*mol^-1)$ $=$ $"approx. "10*mol$ Thus $10$ $mol$ sodium metal are required.

If I start with 25.0 grams of lead (II) nitrate and 15.0 grams of sodium iodide, how many grams of sodium nitrate can be formed?
Pb(NO3)2- Lead Nitrate NaI - Sodium Iodide $Pb(NO_3)_2 + 2NaI --> PbI_2+ 2NaNO_3$ Moles of Lead(II) Nitrate = $mass // molar mass$ = 25.0 grams//(207.20 xx 1 + 14.01 xx...

35.0 grams of thionyl chloride is placed in a glass containing 500.0 grams of water. After the reaction is complete how many grams of water will remain unreacted? How many grams of the thionyl chloride will remain unreacted?
Thionyl chloride reacts quantitatively (and violently) with water as represented by the following reaction: $SOCl_2(l) + 2H_2O(l) rarr SO_2(g)uarr + 2HCl(aq)+Delta$ $"Moles of thionyl chloride"=(35.0*g)/(118.97*g*mol^-1)=0.294*mol.$ And CLEARLY, thionyl chloride is...

Using the following reaction, if 5.93 grams of sodium cyanide are reacted with 8.45 grams of sulfuric acid, how many grams of sodium sulfate will be produced? $2NaCN + H_2SO_4 -> Na_2SO_4 + 2HCN$
This appears to be a limiting reactant problem. 1. Write the balanced equation $"2NaCN" + "H"_2"SO"_4 → "Na"_2"SO"_4 + "2HCN"$ 2. Calculate the moles of $"Na"_2"SO"_4$ formed from...

3 moles of sodium reacted with 3 moles of chlorine gas. How much material was left unreacted? How many moles of sodium chloride were produced?
You need to start by writing the balanced chemical equation that describes the of sodium chloride $color(red)(2)"Na"_ ((s)) + "Cl"_ (2(g)) -> 2"NaCl"_ ((s))$ The balanced chemical...

3.55 moles $H_2$ (g), 1.25 moles $CO$ (g), and an unknown number of moles $N_2$ (g) were placed into a 5.00 L flask at $25.0^oC$. Given the density of this gas mixture to be 19.92 g/L, how many moles of $N_2$ were in the flask?
First start by finding the mass of the gas mixture. $density = (mass )/ (volume)$ $mass = density xx volume$ $mass = 19.92 \ g/L xx 5.00 \ L$ $mass...
