Answer:
<u>136.67 g of Na3PO4 i</u>s required to create 100 gram of NaOH.
Explanation:
The balanced equation:

1 mole Na3PO4 = 164 g/mole (Molar mass)
1 mole NaOH = 40 g/mole (Molar mass)
Now,
1 mole of Na3PO4 produce = 3 mole of NaOH
164 g/mol of Na3PO4 produce = 3(40) g/mol of NaOH
or
120 g/mol of NaOH is produced from = 164 g/mol of Na3PO4
1 g/mol of NaOH is produced from =

100 grams of NaOH is produced from =
gram of Na3PO4
calculate,
= 136.67 g
The first question the mass of Zinc would be 104g
152-64 =88
192-88=104
The second question the mass would be 159g
127+32 =159g
Answer:
<em>(OH-)=2,86 x10 ^-9 M.</em>
Explanation:
Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:
(H3O+) x (OH-) = 1x10^-14
(3.5 × 10^−6) x (OH-)= 1x10^-14
(OH-)= 1x10^-14/(3.5 × 10^−6)
<em>(OH-)=2,86 x10 ^-9 M</em>
