"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

How many grams of fosforic acid (H3PO4) are required to prepare 500 mL of a 0.2 M solution?

navik [9.2K]

Answer:

Mass = 9.8 g

Explanation:

Given data:

Molarity of solution = 0.2 M

Volume of solution = 500 mL

Number of grams of phosphoric acid = ?

Solution:

First of all we will convert the volume milliliter to litter.

500 mL × 1 L/1000 mL

0.5 L

Molarity = moles of solute / volume in litter

0.2 M = number of moles / volume in litter

Number of moles = 0.2 mol/L × 0.5 L

Number of moles = 0.1 mol

Number of grams:

Number of moles = mass/molar mass

Mass = number of moles × molar mass

Mass = 0.1 mol × 98 g/mol

Mass = 9.8 g
