Answer:
How many grams are in 0.50 moles of h2so4?
We assume you are converting between moles H2SO4 and gram. You can view more details on each measurement unit: molecular weight of H2SO4 or grams This compound is also known as Sulfuric Acid. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2SO4, or 98.07848 grams.
Explanation:
The mass of the sample reported is 3.5465 g option e is correct.
Mass is the quantitative measure of the physical body.
The mass of the empty sample container is given as 12 g.
The mass of empty as well as sample containers is given as 15.5465 g.
Therefore, the mass of the sample will be given as :
Mass of sample = mass of a sample as well as empty containers - a mass of empty sample container
= 15.5465 - 12
= 3.5465 g
Therefore, the mass of the sample reported is 3.5465 g option e is correct.

Complete question:
Your question is incomplete, but most probably your full question was, A label on an empty sample container reads 12.00 g. you add in a sample of a compound and the mass of the sample container obtaining 15.5465 g. what should the mass of the sample be reported as?
a) 3.546 g
b) 3.54 g
c) 4 g
d) 4.0 g
e) 3.5465 g
Answer:
The new volume of the balloon is 600cm³
Explanation:
Given parameters:
Initial Volume, which is V₁ = 200cm³
Initial temperature, T₁ = 60°C
Final temperature T₂ = 180°C
Final Volume V₂ =?
To solve this kind of problem, we apply one of the gas laws that shows the relationship between volume and temperature.
This law is the Charles law, it states that " the volume of a fixed mass of a gas is directly proportional to its absolute temperature if pressure is constant".
It is simply expressed as:
V₁/T₁ = V₂/T₂
Since our unknown is V₂, we make it the subject of the expression given above:
V₂ = V₁T₂/T₁
Now input the corresponding values and solve:
V₂ = 200 x 180 / 60
V₂ = 36000/60
V₂ = 600cm³
The new volume of the balloon is 600cm³
Answer:
The name of the two compounds will be:
A :2,2-dimethylbutane
B: 3-methylpentane
Explanation:
The compounds are the isomers of hexane as per the given molecular formula.
There is no unsaturation or no ring is present in the compound.
Constitutional isomers are the one which have different arrangement of chain.
The possible compounds are shown in the figure with the products of monochlorination of the two isomers.
Thus there are five possible isomers of hexane.
A bent
