What’s the volume of the solution?

60.0 mL

General Formulas and Concepts:

Chemistry - Solutions

Explanation:

Step 1: Define

6.33 g CuNO₃

0.840 M Solution

Step 2: Identify Conversions

1 L = 1000 mL

Molar Mass of Cu - 63.55 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CuNO₃ - 63.55 + 14.01 + 3(16.00) = 125.56 g/mol

Step 3: Convert

= 0.050414 mol CuNO₃

Step 4: Find volume

Step 5: Convert

= 60.0168 mL

Step 6: Check

We are given 3 sig figs. Follow sig fig rules and round.

60.0168 mL ≈ 60.0 mL

answer

the ions in solute supperate from eachouthere

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
