Is it necessary to know the exact volume of the unknown acid or base to be titrated?

Darina [25.2K]

Yes, It is important to know the volume of Unknown acid or base to be titrated.

Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.

M₁V₁/n₁ = M₂V₂/n₂

What is the mass of 1 mole of lithium?

Korolek [52]

<u>Answer:</u> The mass of 1 mole of lithium is 6.941 grams.

<u>Explanation:</u>

To calculate the mass of a compound or element, we use the formula used to calculate the number of moles:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Where,

Number of moles of lithium = 1 mole

Given mass of lithium = ? g

Molar mass of lithium = 6.941 g/mol

Putting value in above equation, we get:

$1mole=\frac{\text{Given mass}}{6.941g/mol}\\\\\text{Mass of lithium}=6.941g$

Hence, the mass of 1 mole of lithium is 6.941 grams.

Propane gas reacts with oxygen according to this balanced equation: C subscript 3 H subscript 8 space (g )space plus space 5 spa

Misha Larkins [42]

Explanation:

The balanced chemical equation of the reaction is:

$C_3H_8(g)+ 5O_2 (g)->3CO_2(g)+4H_2O(g)$

From the balanced chemical equation,

1 mole of propane forms ------ 3 mol. of $CO_2$ gas.

The molar mass of propane is 44.1 g/mol.

One mole of any gas at STP occupies --- 22.4 L.

Hence, 44 g of propane forms (3x22.4 L=) 67.2 L of CO2 gas at STP.

Answer:

Thus, 67.2 L of CO2 is formed at STP.
