The mass of the block in kg is 6.65 kg for a rectangular block of tungsten has a length of 7.90 cm, a width of 2.30 cm, and a height of 1.90 cm as the density of tungsten is 19.28.

<h3>What is density?</h3>

Density is the mass of a substance present per unit volume and it is the ratio of mass and the volume of the substance given by gram per centimeter cube.

The mass of tungsten is density multiplied by volume,

                      volume = 7.90 cm × 2.30 cm × 1.90 cm

                        19.28 × 53.53 = 6.65 kg.

Therefore, the density of tungsten is 19.28, and the mass of the block in kg is 6.65 kg for a rectangular block of tungsten has a length of 7.90 cm, a width of 2.30 cm, and a height of 1.90 cm.

Calculate the mass of 29.8 mL of aluminum, which has a density of 2.00 g/mL.
MaRussiya [10]

Answer:

The answer is

<h2>59.6 g </h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

Density of aluminum = 2.00 g/mL

volume = 29.8 mL

The mass is

mass = 2 × 29.8

We have the final answer as

<h3>59.6 g</h3>

Hope this helps you

What happens to the rate of dissolution as the temperature is increased in a gas solution?
Nina [5.8K]

Answer:

The rate decreases

Explanation:

When we dissolve a gas in a water, the process is exothermic. This implies that heat is evolved upon dissolution of a gas in water.

Recall from Le Chateliers principle that for exothermic reactions, an increase in temperature favours the reverse reaction. The implication of these is that when the temperature of the gas is increased, less gas will dissolve in water.

Hence increase in temperature decreases the rate of solubility of a gas in water.
