A 4.24 kg marble slab has the volume of 1564 cm3 What is the density in g/cm3
miskamm [114]

Answer:

The answer is

<h2>2.71 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

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

From the question

volume of marble = 1564 cm³

1 kg = 1000 g

4.24 kg = 4240 g

mass = 4240 g

The density is

density =  \frac{4240}{1564}   \\  = 2.710997442...

We have the final answer as

<h3>2.71 g/cm³</h3>

Hope this helps you

Ammonium chloride is used as an expectorant in cough medicine. It has a density of 1.53 g/cm^3. What is the mass of 26.0L of thi
Katena32 [7]

Answer:

                     39.78 Kg

Explanation:

Data Given;

                  Density  =  1.53 g/cm³

                  Mass  =  <u>??</u>

                  Volume  =  26.0 L  =  26000 cm³

Formula Used;

                       The measure of mass per unit volume is called as density. It is a physical property of a substance and tells how tightly the particles are packed. Mathematically;

                  Density  =  Mass ÷ Volume

Solving for Mass,

                  Mass  =  Volume × Density

Putting values,

                  Mass  =  26000 cm³ × 1.53 g.mL⁻¹

                  Mass  =  39780 g  or   39.78 Kg

The pKa of formic acid is 3.75. At pH of 5.00, _______ .
AlladinOne [14]

The pKa of formic acid is 3.75. At pH of 5.00, b) [formate] > [formic acid].

Formic acid is a weak acid. Thus, together with its conjugate base (formate) they form a buffer system. We can calculate the pH of a buffer system using Henderson-Hasselbach's equation.

pH = pKa + log \frac{[formate]}{[formic\ acid]} \\\\5.00 = 3.75 + log \frac{[formate]}{[formic\ acid]}\\\\\frac{[formate]}{[formic\ acid]}  = 17.8

As expected, at a pH above the pKa, the concentration of formate is higher than that of the formic acid.

The pKa of formic acid is 3.75. At pH of 5.00, b) [formate] > [formic acid].
