What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?

kifflom [539]

Answer: The new concentration of a solution of $CaSO_{3}$ is 0.2 M 10.0 mL of a 2.0 M $CaSO_{3}$ solution is diluted to 100 mL.

Explanation:

Given: $V_{1}$ = 10.0 mL, $M_{1}$ = 2.0 M

$V_{2}$ = 100 mL, $M_{2}$ = ?

Formula used to calculate the new concentration is as follows.

$M_{1}V_{1} = M_{2}V_{2}$

Substitute the values into above formula as follows.

$M_{1}V_{1} = M_{2}V_{2}\\10.0 mL \times 2.0 M = M_{2} \times 100 mL\\M_{2} = 0.2 M$

Thus, we can conclude that the new concentration of a solution of $CaSO_{3}$ is 0.2 M 10.0 mL of a 2.0 M $CaSO_{3}$ solution is diluted to 100 mL.

Convert the density of water, 1.00 g/mL to lb/ft3. Provide only the numerical value in your answer with the correct number of si

PtichkaEL [24]

Answer:

The density of water $1.00 g/ml=62.43 lbs/ft^3$ .

Explanation:

Density of water = 1.00 g/mL

1 lb = 453.592 g

$1 g=\frac{1}{453.592} lbs$

$ft^3=28316.8 mL$

$1 mL=\frac{1}{28316.8} ft^3$

Density of the water in $lb/ft^3$ :

$\frac{1.00 g}{1 mL}=\frac{1.00}{453.592 } lb\times \frac{28316.8 }{1 ft^3}$

$=62.43 lbs/ft^3$

The density of water $1.00 g/ml=62.43 lbs/ft^3$ .

Isocyanic acid, also known as Hydrogen cyanate, is a weak acid and a potentially toxic atmospheric pollutant. Write down the equ

densk [106]

The dissociation of isocyanic acid in water produces its conjugate base, C N- since it will accept a proton to form isocyanic acid.

<h3>What is a conjugate base?</h3>

A conjugate base is a substance which is formed from the loss of the hydrogen ion of an acid and which will act as a base by accepting a proton.

The dissociation of Isocyanic acid in water is given below:

$HC N + H_2O \rightleftharpoons C N^{-} + H_3O^{+}$

The conjugate base is C N- since it will accept a proton to form isocyanic acid.

The number of atoms in 2.50 mol Cr

Slav-nsk [51]

Answer:

1.51 x 10²⁴atoms

Explanation:

Given parameters:

Number of moles of Cr = 2.50mol

Solution;

what is a mole;

a mole of any substance is the amount of substance that contains the avogadro's number of particles which is 6.02 x 10²³ particles

The particles here can be atoms, protons, neutrons, electrons e.t.c

1 mole contains 6.02 x 10²³ atoms

2.5 moles will contain 2.5 x 6.02 x 10²³ = 1.51 x 10²⁴atoms
