During an experiment, 575 mL of neon gas at 101 kPa were compressed in a cylinder to a volume of 144 mL.

Ne4ueva [31]

Answer:

403.3 kPa is the new pressure

Explanation:

This problem is solved by this formula:

P₁ . V₁ = P₂ . V₂

101kPa . 575 mL = P₂ . 144mL

(101kPa . 575 mL) / 144 mL = P₂

403.3 kPa = P₂

"How many formula units are there in sample of copper(II) sulfate that has

babymother [125]

Answer: $1.23\times 10^{23}$ formula units

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:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{32.5g}{160g/mol}=0.203moles$

1 mole of $CuSO_4$ contains $6.023\times 10^{23}$ of formula units

Thus 0.203 mole of $CuSO_4$ contains = $\frac{6.023\times 10^{23}}{1}\times 0.203=1.23\times 10^{23}$ of formula units
