What will the ratio of ions be in any compound formed from a group 1a and a group 7a nonmetals?

1 answer:

4 0

Group 1a elements (the first column on the left side of the Periodic table) always release one electron to form positive ions with a charge of +1. Group 7a nonmetals (the <em>second to the last </em>column on the right side- the rightmost column are the noble gases) always desire to gain one electron to form negative ions with a charge of -1.
Since their charges are equal and opposite, they will always combine in a 1:1 ratio.

Question 6

jolli1 [7]

The molecular weight of the substance is 30.46 g/mol.

<h3>What is molar mass?</h3>

Molar mass can be defined as the mass is divided by the number of moles of the substance.

Step 1: calculating the moles

Given, the mass is 177 g

Pressure is 1.18 atm.

The volume is 2.30 L

By the formula of ideal gas

$\rm PV = nrt\\1.18 \times 2.30 = n \times 8.312 \times 10^-^2 \times 19.0\\\\n = \dfrac{8.312 \times 10^-^2 \times 19.0}{1.18 \times 2.30} = 0.581 \;mol$
