Mass is equal to moles x molar mass, and the molar mass of C6H12 is 84, therefore the mass is 436.8 g, but 437 rounded to correct significant figures
Answer:
There is 17,114825 g of powdered drink mix needed
Explanation:
Step 1 : Calculate moles
As given, the concentration of the drink is 0.5 M, this means 0.5 mol / L
Since the volume is 100mL, we have to convert the concentration,
⇒0.5 / 1 = x /0.1 ⇒ 0.5* 0.1 = x = 0.05 M
This means there is 0.05 mol per 100mL
e
Step 2 : calculate mass of the powdered drink
here we use the formula n (mole) = m(mass) / M (Molar mass)
⇒ since powdered drink mix is usually made of sucrose (C12H22O11) and has a molar mass of 342.2965 g/mol.
0.05 mol = mass / 342.2965 g/mol
To find the mass, we isolate it ⇒0.05 mol * 342.2965 g/mol = 17,114825g
There is 17,114825 g of powdered drink mix needed
When you see or visit grasslands you know that :
- They have mild to hot summers ( B )
- They have a lot of precipitation ( A )
<h3><u>Grassland vegetation</u> </h3>
Grasslands are a type of vegetation found mostly in areas with favourable weather conditions such as mild summers and right amount of precipitation which provides the grasslands with enough water for proper growth.
Other types of vegetation include :
- Forest vegetation
- Tundra and
- Desert vegetation
Desert vegetation expreciences very hot summers and little precipitation which leads to the scarcity of green vegetation, while forest vegetation expreciences a very high level of precipitation.
Hence we can conclude that When you see or visit grasslands you know that :They have mild to hot summers ,They have a lot of precipitation

Yes you are choosing the right one because the sodium hydroxide with sulfuric acid is the correct answer
Explain in terms of particle behavior why smoke particles cause the detector alarm to sound
Smoke detectors are of many types but they rely on the principle of diffusion of smoke. Diffusion is the movement of particles from a region of high concentration to a region of lower concentration. Smoke particles move in what is known as Brownian motion.
