List the grams of bleach solution necessary to provide 0.931g of NaClO(laundry bleach is 8.25% NaClO by weight) and the mL of bleach solution that contains the necessary amount... NaClO=74.442 g/mol. Need 0.931 grams of NaClO. Density of NaClO solution is 1.07 g/ml
To calculate the grams of bleach solution necessary to provide 0.931g of NaClO, you need to consider the composition of the bleach and the molar mass of NaClO.
First, let's determine the amount of NaClO in the given weight of bleach. Since the bleach is 8.25% NaClO by weight, we can calculate it as follows:
0.931g NaClO = 0.0825 (percentage) × grams of bleach solution
Solving for the grams of bleach solution:
grams of bleach solution = 0.931g NaClO ÷ 0.0825
grams of bleach solution = 11.28g
So, you will need 11.28 grams of bleach solution to provide 0.931g of NaClO.
Next, let's calculate the volume of bleach solution required using the density of NaClO solution. The density is given as 1.07 g/ml, which means that for every 1 ml of bleach solution, you have 1.07 grams of it.
Since we need 11.28 grams of bleach solution, we can calculate the volume using the density:
volume of bleach solution = grams of bleach solution ÷ density
volume of bleach solution = 11.28g ÷ 1.07 g/ml
volume of bleach solution ≈ 10.5 ml
So, you will need approximately 10.5 ml of bleach solution to provide the necessary amount of NaClO (0.931g).
