Answer:

5 cm³.

Explanation:

From the question given above, the following data were obtained:

Volume of water = 35 mL

Volume of water + Rock = 40 mL

Volume of Rock =.?

The volume of the rock can be obtained as follow:

Volume of Rock = (Volume of water + Rock) – (Volume of water)

Volume of Rock = 40 – 35

Volume of Rock = 5 mL.

Finally, we shall convert 5 mL to cm³.

This can be obtained as follow:

1 mL = 1 cm³

Therefore,

5 mL = 5 mL × 1 cm³ / 1 mL

5 mL = 5 cm³

Thus, we can say that the volume of the rock is 5 cm³.

20 ml of a solution of sucrose contains 850 mg of sucrose. What is the weight/volume percentage concentration of this solution i
MissTica
<h3>Answer:  4.25 g/ml %</h3>

Explanation:

weight/volume percentage concentration = (mass in g  ÷  volume) × 100

                                                                      =  (0.850 g ÷ 20 ml) × 100

                                                                      = 4.25 g/ml %

∴ the weight/volume percentage concentration of the sucrose solution is 4.25 g/ml %.

A sample of argon gas at 55°C is under 845 mm Hg pressure. What will the new temperature be if the pressure is raised to 1050 mm
Maurinko [17]

Answer:

The final temperature at 1050 mmHg is 134.57 ^{\circ}C or 407.57 Kelvin.

Explanation:

Initial temperature = T = 55^{\circ}C = 328 K

Initial pressure = P = 845 mmHg

Assuming final  to be temperature to be T' Kelvin

Final Pressure = P' = 1050 mmHg  

The final temperature is obtained by following relation at constant volume

\displaystyle \frac{P}{P'}=\displaystyle \frac{T}{T'} \\ \displaystyle \frac{845 \textrm{ mmHg}}{1050 \textrm{ mmHg}} = \displaystyle \frac{328 \textrm{ K}}{T'} \\T' = 407.57 \textrm{ Kelvin}

The final temperature is 407.57 K
