Determine the equivalent mass
In the above compound, we have: 2 Al and 3 (O)
The atomic mass of Aluminium is:
The atomic mass of Oxygen is:
So, the equivalent mass is:
Answer:
Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate as follows:
Volume = 60.0 g ( 1 mL / 0.70 g ) = 85.71 mL
Therefore, the correct answer is option B.
Explanation:
They should report the density as 1.11 g/L
.
Density = mass/volume = 2.260g/2.04 mL
My calculator says the density <em>1.107 843 137 g/mL</em>
However, the answer can have <em>no more</em> significant figures than are in the number with the <em>fewest </em>significant figures.
The volume measurement has only three significant figures, so we must round off the density to three significant figures.
We drop all the digits after the zero.
The digit to be dropped is 7, so we <em>round up </em>the last significant figure of the answer.
1.10<u>7 843 137</u> → 1.11

I guess you just answered a lot of questions

Thanks for the points btw :)
Answer: Conduction
Explanation:
Because the ice cube is touching the surrounding soup, the energy is going from the hot soup into the ice cube. You can rule out radiation and convection because radiation includes rays (which aren't a part of this question) and convection is usually seen in objects/fluids that are not touching (and the ice cube and the soup ARE touching).
