The density of a gold nugget is 19.3 g/cm3. If the volume of the gold nugget is 0.00369 L the mass of the nugget is
Sauron [17]

Answer:

The answer to your question is 71.22 g

Explanation:

Data

Density = 19.3 g/cm³

Volume = 0.00369

mass = ?

Formula

Density = \frac{mass}{volume}

Solve for mass

mass = density x volume

Process

1.- Convert volume from liters to cubic centimeters

                 1 l ----------------  1000 cm³

             0.00369l ---------   x

                x = (0.00369 x 1000 ) / 1

                x = 3.69 cm³

2.- Substitution

       mass = 19.3 x 3.69

3.- Simplification and result

       mass = 71.22 g

Which would have a higher pH, a 0.1 M solution of a strong acid, or a weak acid? Why?
DerKrebs [107]

Answer:

0.1 M weak acid

Explanation:

The term pH simply means power of hydrogen which is basically a log (the exponent to base 10 of the concentration) of the concentration of the hydrogen ions.

Weak acids have a higher pH since their hydrogen concentration is lower than that of strong acids.

Which statement must be true for any chemical reaction at equilibrium?
sergejj [24]
<span>The correct answer is 3. The concentration of the product and the concentration of the reactants are equal. That is because matter cannot be created or destroyed and the product cannot randomly become something else in the reaction, nor can a reactant change into something different. Simply put, you cannot turn things like water into gold because there will always be an equilibrium.</span>
