How many grams of calcium nitrate needs to be added to 400g of water to make a solution that is 12.5 percent by mass of calcium nitrate?

Call the unknown mass m. Then, from the problem statement, m/(400 + m) = 12.5 % = 0.125. Applying standard algebra techniques, multiply both sides of this equation by (400 + m) to result in m = 0.125(400 + m); m(1 - 0.125) = 400 X 0.125; 0.875m = 50; m = 57.1 grams, to the justified number of significant digits.

When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs?
The products of the reaction are solid calcium sulfate and aqueous lithium nitrate.
What happens when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube?
Lead iodide (Pb2I) precipitates as a yellow solid, leaving a solution of potassium and nitrate ions.
What happened silver nitrate added ammonium chloride?
If the silver nitrate and ammonium chloride are both in solution when mixed, the very sparingly soluble silver chloride precipitates as a solid, leaving ammonium nitrate in the solution.
What happens when silver nitrate solution is added to potassium iodide solution?
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
What is observed when a solution of potassium iodide is added to silver nitrate solution?
A yellow precipitate of silver iodide (AgI).
When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs?
The products of the reaction are solid calcium sulfate and aqueous lithium nitrate.
What is the chemical reaction of a solution of lead nitrate is added to a solution of potassium sulfate?
Lead nitrate + potassium sulfate ---> Lead sulfate + Potassium nitrate
What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
What will be the observations when Zinc nitrate solution is added to Lead nitrate solution?
When zinc nitrate solution is added to lead nitrate solution you willÊapparently observe a black solid being formed. All of the research yielded facts from adding solid metal to either zinc or lead.
Would calcium nitrate and magnesium react?
Calcium nitrate and magnesium will not react since calcium is more reactive than magnesium and so, magnesium does not displace calcium (See Reactivity Series). However, if Calcium nitrate is in aqueous solution (dissolved in water), some bubbles may be seen when Magnesium is added to it, since the Magnesium would be reacting with the water and producing hydrogen bubbles.
What happens when sodium nitrate is added to calcium chloride?
Any reaction occur.
When lead nitrate solution is added to potassum iodide solution what gas does it emit?
it doesn't
What will happen if ammonium nitrate and calcium hydroxide is added at the same time?
Nothing. They do not react.
What happens when you add silver nitrate to distilled water and to salt solution?
Silver nitrate will dissolve in distilled water. When added to a salt solution silver chloride will fall out of solution.
What happens when barium nitrate solution is added to zinc sulphate solution?
Sh!t happens.
Will a reaction occur if cu is added to silver nitrate solution?
None
What is result when silver nitrate is added to a starch?
The solution turns purple.
