Answer:

According to Gas Law

Volume is inversely proportional to pressure, if the number of particles and the temperature are constant. There are two ways for the pressure to remain the same as the volume increases.

klio [65]

Answer:

Distance = 154 pm

Explanation:

Given that,

The distance between carbon atoms in diamond is $1.54\times 10^{-8}\ cm$

We need to find the distance in pm.

We know that,

$1\ pm=10^{-12}\ m$

$1.54\times 10^{-8}\ cm=1.54\times 10^{-8}\times 10^{-2}\ m\\\\=1.54\times 10^{-10}\ m$

Multiplying and dividing by 10⁻².

$d=1.54\times 10^{-10}\times \dfrac{10^{-2}}{10^{-2}}\\\\=154\times 10^{-12}\ m\\\\=154\ pm$

So, the distance is 154 pm.

1. How many molecules of barium hydroxide, Ba(OH)2 are there in 21.9 grams of

vladimir2022 [97]

Answer: $7.7\times 10^{22}$ molecules of $Ba(OH)_2$

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{21.9g}{171g/mol}=0.128moles$

1 mole of $Ba(OH)_2$ contains = $6.023\times 10^{23}$ molecules

0.128 mole of $Ba(OH)_2$ contains = $\frac{6.023\times 10^{23}}{1}\times 0.128=7.71\times 10^{22}$ molecules

Thus there are $7.7\times 10^{22}$ molecules of $Ba(OH)_2$
