Ksju [112]3 years ago
6 0

Answer:

<h3>The answer is 0.79 g/mL</h3>

Explanation:

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

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

From the question

mass = 2.56 g

volume = 3.25 mL

We have

density =  \frac{2.56}{3.25}  \\  = 0.78769230...

We have the final answer as

<h3>0.79 g/mL</h3>

Hope this helps you

why do you think you can find silver and gold on their own in rocks but calcium and magnesium are combined with other elements t
katrin [286]

Explanation:

Silver and Gold belong to a special group of metals known as the native metals. They are found naturally on their own and not in combined form in rocks.

  • These metals are found uncombined because they are unreactive.
  • They prefer to alloy with themselves.
  • Calcium and magnesium on the other hand are reactive metals.
  • The unreactivity of these metals makes them uncombined in nature.

Suppose you have 15.0 ml of zinc. What volume of aluminum would have the same mass as the zinc?
Black_prince [1.1K]

Answer:

\large \boxed{\text{41.2 cm}^{3}}

Explanation:

1. Mass of zinc

The density of zinc is 7.14 g/cm³

D = m/V

\begin{array}{rcl}7.14 & = & \dfrac{m}{15.0}\\\\m & = & 7.14 \times 15.0\\& = & \text{107.1 g}\\\end{array}\\

2. Volume of aluminium

The density of aluminium is 2.60/cm³.

\begin{array}{rcl}2.60 & = & \dfrac{107.1}{V}\\\\2.60V & = & 107.1\\V& = &\dfrac{107.1}{2.60}\\\\& = &\textbf{41.2cm}^{\mathbf{3}}\\\end{array}\\\large \boxed{\textbf{41.2 cm}^{\mathbf{3}}}\text{ of aluminium have the same mass as 15.0 cm$^{3}$ of zinc.}
