Answer:
0.1159 M
Explanation:
Using the formula below:
CaVa = CbVb
Where;
Ca = concentration/molarity of acid (M)
Cb = concentration/molarity of base (M)
Va = Volume of acid (mL)
Vb = volume of base (mL)
According to this question, the following information were given:
Ca = ?
Cb = 0.2831 M
Va = 26.86 mL
Vb = 11.00 mL
Using CaVa = CbVb
Ca × 26.86 = 0.2831 × 11
26.86Ca = 3.1141
Ca = 3.1141 ÷ 26.86
Ca = 0.1159
The molarity of the acid (H2SO4) solution is 0.1159 M
Answer:
Atoms with 5 or more valence electrons gain electrons forming a negative ion, or anion. why are outermost electrons only ones included in orbital filling diagram? they are the only ones involved in chemical reactions and bonding. ... 2s orbital is farther from the nucleus meaning it has more energy.

Answer:
0.098 moles
Explanation:
Let y represent the number of moles present
1 mole of Ba(OH)₂ contains 2 moles of OH- ions.
Hence, 0.049 moles of Ba(OH)2 contains y moles of OH- ions.
To get the y moles, we then do cross multiplication
1 mole * y mole = 2 moles * 0.049 mole
y mole = 2 * 0.049 / 1
y mole = 0.098 moles of OH- ions.
1 mole of OH- can neutralize 1 mole of H+
Therefore, 0.098 moles of HNO₃ are present.
