2.95g of sodium bicarb how much water to add to make 1.0 M solution
4.25g of Sodium carbonate how much water to add to make 1.0 M solution.
Please show all the work very clearly even little steps to help me understand.
"You need to create a 1.0 M solution of sodium bicarbonate (NaHCO3 – baking soda). Your lab kit has a bag of sodium bicarbonate to use for this portion of the experiment.
thank you
2.95g of sodium bicarbonate how much water to add to make 1.0 M solution
answer
given mass of sodium bicarbonate ( solute) = 2.95g
molar mass of sodium bicarbonate = NaHCO3 = 23+1+12+(16×3) =84
Number of moles = = = 0.035
Molarity of the solution = 1.0M
formula to calculate molarity = =
1.0 =
Volume of solution in liters = 0.035 L
Volume of solution in millilitres =0.035 ×1000= 35mL
therefore 35mL of water is added in 2.95g of NaHCO3 to make a solution of 1.0M
Question : 4.25g of Sodium carbonate how much water to add to make 1.0 M solution.
Answer :
Given mass of sodium Carbonate = 4.25g
Molar mass of sodium Carbonate = (23×2)+12+(16×3)= 106
Number of moles of sodium Carbonate = 0.04 moles
Molarity of the solution = 1.0M
Formula for calculating molarity is
1.0 =
Volume of solution in liters= 0.04
Volume of solution in millilitres = 0.04× 1000= 40 mL
therefore 40 mL of water is added to 4.25 g of sodium Carbonate to make solution of 1.0 M

Use the 10 mL gradated cylinder to measure and pour 1 mL of saturated sodium bicarbonate solution into Beaker 1. Then, add 2 drops of phenol red to Beaker 1. Gently mix the solution. Use the straw to blow bubbles into Beaker 1. Start...
how much distilled water do I have to add to 2.5 g of Na2CO3 and 2.5 g NaHCO3 to make a 1.0 M of each?
You need 100 mL of a 0.00057 M solution for an experiment. You are given 10 mL of a 5.7 M stock solution. What is the best method to get the final volume and concentration you for trial? -It is not possible to reach that concentration with the info presented. -Use a 1.0 mL volumetric pipette and then dilute with water to 100 mL, then repeat serially until the desired concentration is reached. -Use a graduated cylinder to measure 0.1...
Experiment 1: Neutralization of Acids and Bases In this experiment, you will learn how to properly neutralize and dispose of acidic and base solutions. Remember, when a solution has a pH of 7, it is considered neutralized.

Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HC1), which the stomach secretes to help digest food. Drinking a glass of water containing dissolve NaHCO3 neutralizes excess HCl through this reaction: HCI(aq) NaHCO3(aq) → NaCl(aq) + H,O() + CO2(g) The CO2 gas produced is what makes you burp after drinking the...
The aluminum cup inside your calorimeter weighs 41.55 g. You add 59.21 g of 1.0 M acetic acid solution and 50.03 g of 1.0 M sodium hydroxide solution to the calorimeter. Both solutions have an initial temperature of 19.9 °C, and the final temperature after addition is 26.8 °c. What is the molar enthalpy of neutralization, in units of kJ/mol? Assume that: the calorimeter is completely insulated the heat capacity of the empty calorimeter is the heat capacity of the...
