Answer:

<h2>The answer is 1.99 g/mL</h2>

Explanation:

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

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

From the question

mass of acid = 60.19 g

volume = 30.2 mL

The density is

$density = \frac{60.19}{30.2} \\ = 1.993046357...$

We have the final answer as

Hope this helps you

Name and explain the two types of atom bonding

nordsb [41]

Ionic bonding which is the attraction between the cations(metal) and anions (non metal).

Metallic bonding is the electrostatic force of attraction between the fixed cations and the delocalized electrons.

A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 273. kPa.

P2 = 54.6 kPa

Explanation:

Given:

V1 = 10.0 L. V2 = 50.0 L

P1 = 273 kPa. P2 = ?

We can use Boyle's law to solve this problem.

P1V1 = P2V2

Solving for P2,

P2 = (V1/V2)P1

= (10.0 L/50.0 L)(273 kPa)

= 54.6 kPa
