What is the [H+] in a solution with pOH of 0.253?
sergey [27]
PH + pOH = 14

pH + 0.253 = 14

pH = 14 - 0.253

pH = 13.747

[ H+] = 10 ^ -pH

[ H+ ] = 10 ^- 13.747

[ H+ ] = 1.790x10⁻¹⁴ M

hope this helps!

A volume of 25.36 ± 0.05 mL 25.36±0.05 mL of HNO 3 HNO3 solution was required for complete reaction with 0.8311 ± 0.0007 g 0.831
Sholpan [36]

Answer:

MOLARITY= 0.3092mol/l

ABSOLUTE UNCERTAINTY= 0.000873

Explanation:

The equation of reaction is

2HNO3 + Na2CO3 ⟶ 2NaNO3 + H2O + CO2.

QUESTION1: CALCULATION FOR MOLARITY;

Molarity= gram mole of solute ÷ liters of solution

Where;

Mole of solute= mass ÷ molar mass

Therefore;

Mole of solute= 0.8311g ÷ 105.988g/mol= 0.0078515mol

MOLARITY= 0.0078415mol ÷ 25.36ml = 0.0003092mol/ml = 0.3092mol/l

This is the Molarity of the solution

QUESTION2: CALCULATION FOR ABSOLUTE UNCERTAINTY;

Uncertainty (u) =√([0.05 ÷ 25.36]^2 + [0.001 ÷ 105.988]^2 + [0.0007 ÷ 0.8311]^2) × Molarity

Solving brackets gives

(0.00197161+0.00000943503+0.00084226) ×Molarity

Adding up gives

0.002823×Molarity

Therefore;

ABSOLUTE UNCERTAINTY= 0.002823×0.3092= 0.000873

Formula D = m / V m = 22 g D = 4 g/mL What is the Volume of the object in mL? Do not include the units in your answer.
Lemur [1.5K]

Answer:

The answer is

<h2>5.50</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass = 22 g

density = 4 g/mL

The volume is

volume =  \frac{22}{4}  =  \frac{11}{2}  \\

We have the final answer as

<h3>5.50 mL</h3>

Hope this helps you
