Answer is: <span>the approximate molar mass of a molecular solute is 150 g.
</span>m(molecular solute) = 300 g.
m(water) = 1000 g ÷ 1000 g/kg = 1 kg.
ΔT = 101°C - 100°C = 1°C.
M(molecular solute) = Kb · m(molecular solute) / m(water) · ΔT.
M(molecular solute) = 0,512°C/m · 300 g / (1 kg · 1°C).
M(molecular solute) = 153,6 g/mol.
Answer:
16.4moles
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms.
This clearly indicates that 1mole of (NH4)3PO4 also contains 6.02x10^23 atoms.
Now, if 1mole of (NH4)3PO4 contains 6.02x10^23 atoms,
Then Xmol of (NH4)3PO4 will contain 9.87X10^24 atoms i.e
Xmol of (NH4)3PO4 = 9.87X10^24/6.02x10^23 = 16.4moles
B. When melted, the chocolate will take the shape of the bowl.
Explanation:
The chocolate chips are heated in the bowl, they will assume the shape of the bowl or container they are placed in.
- They simply undergo a phase change from solids to liquids.
- Solids generally have fixed volume with their rigid shapes.
- Liquids and gases takes up the shape of the container they are placed in.
- Baring no loss of chocolate, the weight will remain the same because weight is function of mass and gravity. Gravity will remain the same, and the amount of matter, the mass will also be the same.

Answer:
decomposers
Explanation:
I'm not sure weather your supposed to create an actual experiment or write a paper. If an experiment, test certain acids to see which one can decompose plastics the fastest and determine which one can be spread through the oceans to melt down plastic. If a paper, discuss the idea of genetically modified fish. Some animals in the wild have the ability to eat pollution (wrappers, bottles, ect.), so mutating fish such as bottom feeders to be able to do the same would easily rid the water of pollution and make for one interesting of a paper! hope this sort of helped!
Each of the organic compounds mentioned has a general formula so that we can identify the classification of a certain substance. The compound CH₃CH₂OH is an alcohol because it follows the general formula R-OH, where R is a hydrocarbon chain. In this case, the hydrocarbon chain is ethane. When a hydroxyl functional group is attached, it becomes an alcohol whose name is ethanol.
