Answer:

d = 1.8 g/mL

Explanation:

Given data:

Mass of bottle = 6.8 g

Volume of liquid = 23.1 mL

Mass of bottle + liquid = 48.8 g

Density of liquid = ?

Solution:

First of all we will calculate the mass of liquid.

Mass of liquid = combined mass - mass of bottle

Mass of liquid = 48.8 g - 6.8 g

Mass of liquid = 42 g

Density of liquid:

d = m/v

d = 42 g/ 23.1 mL

d = 1.8 g/mL

I need help with Chemistry: Mole Conversion<br> It must be answered in complete detail
Anni [7]

Answer:

As Per Given Information

Number of moles SO₂ ( Sulphur dioxide ) is 0.30

We 've been asked to find the number of atoms in given moles of Sulphur dioxide .

Value of Avogadro Number is 6.022 × 10²³ mol⁻¹

For finding the number of atoms we will use formale

\underline{\boxed{\textbf{\textsf{ Number \: of \: atoms \:  = Given \: moles \:  . Avogadro \: number}}}}

Putting the given value we obtain

\sf \twoheadrightarrow \: Number \: of \: atoms \:  = 0.30 \times 6.022 \times  {10}^{  23}    \\  \\ \sf \twoheadrightarrow \: Number \: of \: atoms \:  = \: 1.8066 \times  {10}^{ 23} atoms

So, the number of atoms in sulphur dioxide is 1.8066 × 10²³

1) How much energy would be required to melt 15.0 g of ice at 0°C?
DerKrebs [107]

Answer:

5010J

Explanation:

The following data were obtained from the question:

Mass (m) = 15g

Heat of fusion (ΔHf) = 334J/g

Heat required (Q) =..?

The heat energy required to melt the ice can be obtained as follow:

Q = m·ΔHf

Q = 15 x 334

Q = 5010J

Therefore, the heat energy required to melt the ice is 5010J.
