Find the density of a material, given that a 5.01 g sample occupies 3.46 mL

Alex73 [517]

Answer:

The answer is

Explanation:

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

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

From the question

mass of material = 5.01 g

volume = 3.46 mL

The density of the material is

$density = \frac{5.01}{3.46} \\ = 1.44797687...$

We have the final answer as

Hope this helps you

2. How many grams of NaCl are required to prepare 0.40 L of a 0.75 M solution?

Yuri [45]

The mass of a NaCl solution that is required to prepare 0.40 L of a 0.75 M solution is 17.55g. Details about mass can be found below.

<h3>How to calculate mass?</h3>

The mass of a substance can be calculated by multiplying the number of moles by its molar mass.

However, the number of moles of a solution must be initially calculated by using the following formula:

molarity = no of moles ÷ volume

no of moles = 0.75 × 0.40

no of moles = 0.3 moles

mass of NaCl = 0.3 × 58.5 = 17.55g

Therefore, the mass of a NaCl solution that is required to prepare 0.40 L of a 0.75 M solution is 17.55g.

Why do atoms share electrons in covalent bonds??

ra1l [238]

Atoms in covalent bonds do combine so as to be stable. As covalent bond consist non metals e.g O2 in this example each atom has vacance of 2 orbitals/ electrons so shairing electrons result their stability
