Answer:
318.749g
Explanation:
The find the mass,
We use this formula
Number of mole = mass/ molar mass
Since number of mole = 3.25mol
Let the number of mass be x
The molar mass of H2SO4
H - 1.00784 * 2= 2.01568
S - 32.065
O - 15.999 * 4 = 63.996
Note there are 2 moles of H and 4 moles of O and 1 mole of S
Molar mass of H2SO4 = 2.01568 + 32.065 + 63.996
= 98.07668g/mol
Number of mole= 3.25mol
3.25 = x / 98.07668
x = 3.25 * 98.07668
x= 318.749g
Hence, the number of mass is 318.749g

All processes for which the temperature stays constant are described by Boyle's law.
Boyle's law is expressed as p1 * V1 = p2 * V2, where p1 and V1 are starting pressure and volume, respectively. The ultimate values of these gas parameters are p2 and V2.
Boyle's law formula can be stated in a variety of ways, depending on the parameter we want to estimate. Let's imagine we wish to determine the pressure that results from changing a gas' volume under isothermal conditions. The Boyle's law equation thus reads: p2 = p1 * V1 / V2 or p2 / p1 = V1 / V2.
As we can see, the final-to-initial pressure ratio is the opposite of the volume ratio.

It is FALSE. The alcohol or alwa ok functional group has a general formula of;
CnH₂n₊₁OH
Although, Carbkn is present in the alcohol group, it is not part of the functional group. The functional group is called hydroxyl group. And it is represented as OH. This means that it consists only of Oxygen and Hydrogen.
Hope that helped. Have a nice day
Answer:
copper sulphate reacts with sodium hrydroxide to form a blue preipitate of copper hrydroxide and soduim hrydroxide.
Answer:
5 g of H₂ are contained in the vessel
Explanation:
A typical excersise of conversion:
We determine molar mass of H₂.
This is a dyatomic molecule, as molar mass of H is 1g/mol, molar mass of H₂ will be 2g/mol.
Let's make the conversion of units:
2.5 mol . 2g/mol = 5 g
5 g of H₂ are contained in the vessel
