Answer:
A tutorial, in education, is a method of transferring knowledge and may be used as a part of a learning process. More interactive and specific than a book or a lecture, a tutorial seeks to teach by example and supply the information to complete a certain task.
At STP, one mole of gas occupies 22.4 L of space. Assuming the conditions conform to STP
volume CO2 = 0.5 mol * 22.4 L/1 mol
= 11.2 L
= 10 L
The answer with 1 significant figure is 10 L of CO2
Answer:
The "right" answer is 4. When matter is a gas, the particles flow freely, having no fixed shape or volume and contain a lot of extra space between particles.
However the last part, "...with a lot of empty space between them giving it energy" is (I'm fairly certain) incorrect. The relationship is the other way. Energy is added to the system, causing the particles to move more, thus building up the space between them.
Answer:
49.14 carat.
Explanation:
From the question given above, we obtained the following data:
Volume of diamond = 2.8 mL
Mass of diamond (in carat) =.?
Next, we shall determine the mass of diamond in grams (g). This can be obtained as follow:
Volume of diamond = 2.8 mL
Density of diamond = 3.51 g/mL
Mass of diamond ( in grams) =?
Density = mass /volume
3.51 = mass /2.8
Cross multiply
Mass of diamond (in g) = 3.51 × 2.8
Mass of diamond (in g) = 9.828 g
Finally, we shall Convert 9.828 g to carat. This can be obtained as follow:
1 g = 5 carat
Therefore,
9.828 g = 9.828 g /1 g × 5 carat
9.828 g = 49.14 carat.
Therefore, the mass of the diamond in carat is 49.14 carat.
