8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
0.2 mol
The mass is 467,52 g.
0,666 moles
We need 8 moles potassium chloride.
The answer is 7,18.10e-10 moles.
0.2 mol
The mass is 467,52 g.
Sodium chloride has a molar mass of about 58.5 g/mol. So multiply 8 moles by molar mass to get about 468 grams.
pH is 8
1. Sodium hydroxide 2. Pottassium hydroxide 3. Ammonium hydroxide 4. Calcium hydroxide 5. First base 6. Second base 7. Third base 8. The base of a triangular pyramid.
If substance has a Ph greater than 7, it is Sodium Bicarbonate and Sodium Hydroxide. Sodium Bicarbonate = 8 Sodium Hydroxide = 14
Sodium (Na), oxygen (O) and hydrogen (H).
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz

Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus
0,666 moles
n=CV/1000 Where n = number of moles, C= Molarity concentration of the solution, and V= volume of the solution in milliliter's We are given, n=0.150, V=8.16 liters(8160 milliliters)and C is not given. Solving for C from the equation above we get: C=(n*1000)/V C= (0.150*1000)/8160 C= 0.018 The molarity of the solution is 0.018
