How do you make a 4\% NaOH solution?
——–> 50 ml The Weight in grams of NaOH needed to prepare 4\% NaOH is = (4 x 50)/100 = 2 g. So, 2 grams of NaOH is dissolved in little water and the volume made up to 50 ml. W/W\% → Weight/Weight Percentage Concentration. W/W\% define as: the number of grams of solute dissolved in 100 gram of solution.
What is the molarity of 5\% NaOH solution?
1.25 M.
FREE Expert Solution The molarity of a 5.00 \% w/v NaOH is 1.25 M.
What is the molarity of 7\% NaOH?
0.4M.
Therefore, the molarity of the solution containing 7g of NaOH will be 0.4M.
What is the molarity of 5 g of NaOH in 450 mL solution?
Answer Expert Verified =0.277777777778=0.28(approx.)
What is the molarity of sodium?
In chemistry, the units of moles/L are called molarity, with the abbreviation M. Thus we could say that our saturated solution of sodium chloride was 6.14 molar, or 6.14 M.
What is the molarity of 6\% NaOH solution?
0.05⋅mol⋅L−1 .
How do you calculate the concentration of the NaOH solution?
Determine[OH -]Every mole of NaOH will have one mole of OH -.
How do you find the molar mass of NaOH?
The molar mass of NaOH is the weight in grams of one mole and one mole has 6.022 x 1023 entities. Therefore, the molar mass of NaOH is the mass in grams of 6.022 x 1023 entities. To get molar mass of NaOH all you need to do is find its molecular weight and stick the unit “g/mol” after that number.
How to dilute NaOH?
If you do get NaOH on your skin, immediately rinse it with a large volume of water. Another option is to neutralize any base on the skin with a weak acid, such as vinegar, and then rinse with water. Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter.
How many moles of NaOH are needed to neutralize the acid?
It takes 4.8 moles of sodium hydroxide (NaOH) to neutralize 2.4 moles of sulfuric acid (H2SO4). The process for solving the correct number of moles of NaOH involves the use of the mole ratio between NaOH and H2SO4.
