Laws of conservation of mass/pleases help

umka2103 [35]

Answer:

27g + 33g = 60g

18g + 24g = 42g

Explanation:

The law of conservation of mass states that no matter can be destroyed or created. Because of this, you are simply making both sides equal.

What mass of AlCl3 is dissolved in 330 cm if the concentration of the solution is 283<br>gdm 3?

nalin [4]

Mass of AlCl₃ : 93.39 g

<h3>Further explanation</h3>

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

$\large {\boxed {\bold {M ~ = ~ \dfrac {n} {V}}}$

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

So to find the number of moles can be expressed as

n = V x M

the volume of the solution = 330 cm³=0.33 dm³

the concentration of the solution = 283 g/dm³

mass of AlCl₃ :

$\tt mass=V\times M\\\\mass=0.33\times 283=93.39~g$

Convert 26.02 x 1023 molecules of C2H8 to grams. Round your answer to the hundredths place.

aliina [53]

Answer:

x= 138.24 g

Explanation:

We use the avogradro's number

6.023 x 10^23 molecules -> 1 mol C2H8

26.02 x 10^23 molecules -> x

x= (26.02 x 10^23 molecules * 1 mol C2H8 )/6.023 x 10^23 molecules

x= 4.32 mol C2H8

1 mol C2H8 -> 32 g

4.32 mol C2H8 -> x

x= (4.32 mol C2H8 * 32 g)/ 1 mol C2H8

x= 138.24 g
