Answer:

341.97 g/mol

Explanation:

Let us first write down the relative atomic masses of all the elements involved. (Please not that these will differ from periodic table to periodic table. Familiarize yourself with the data sheet in your institution)

Al - 26.892

S - 32.066

O - 15.999

From the formula we can see that we

Two aluminium atoms = 26.892*2 = 53.784

Three sulphur atoms = 32.066*3 = 96.198

Twelve oxygen atoms  = 191.988

Add them all up = 341.97

So the molar mass is 341.97 g/mol. The units have to assigned because this is the molar mass. Relative molecular mass has not units

DIA [1.3K]

Answer:

Specific heat of solid A is greater than specific heat of solid B.

Explanation:

In the calorimeter, as the temperature is increasing, the vibrational kinetic energy will increase and this means that additional amount of energy will be needed to increase the temperature by the same value. Therefore, we can conclude that specific heat increases as temperature increases.

Now, we are told that the final temperature of solid A's calorimeter is higher than that of B.

This means from our definition earlier, Solid A will have a higher specific heat that solid B.

ElenaW [278]

Answer:

<h2>chemoautotrophs</h2>

Explanation:

Such types of bacteria that oxidize inorganic compounds to obtain energy and use carbon dioxide as a carbon source to synthesize their food are known as chemoautotrophs such as iron-oxidizing bacteria, cyanobacteria, sulfur-oxidizing bacteria and some other. Chemoautrophic mode of nutrition is a type of autotrophic nutrition in which organisms have the ability to synthesized their own food by using chemical energy in the place of solar energy. The organismS that use solar energy to synthesize their food are known as photoautotrophic organisms such as plants and some other organisms.
