Answer: 0.450 M H2SO4
Explanation:
To solve this problem, we must remember how to compute molarity. To find the molarity of a solution, we divide the number of moles by the number of liters of solution. Using this formula and substituting the given values, we get:
Molarity = moles solute/liters solution
= 1.35 moles/3.00 L
= 0.450 M H2SO4
Therefore, the correct answer is 0.450 M H2SO4. Note that the answer has 3 significant figures because each of the given values also contains 3 significant figures.
Hope this helps!
Answer:
380.5g/mol
Explanation:
The molar mass of a compound can be obtained by adding the molar masses of the elements present in the compound.
The molar mass of Cu3(PO4)2 can be obtained as follow:
Molar Mass of Cu = 63.5g/mol
Molar Mass of P = 31g/mol
Molar Mass of O = 16g/mol
The molar mass of Cu3(PO4)2 = (63.5x3) + 2[31 + (16x4)] = 190.5 + 2[31 + 64] = 190.5 + 2[95] = 190.5 + 190 = 380.5g/mol
The combination of decay processes that would convert U-239 into PU- 239 is beta decay followed by another beta decay. Beta decay involves the emission of an electron [positron]. There are two types of beta decay; positive and negative beta decays and both occur simultaneously in order to move the atoms towards stability.
Neutron is a neutral particle which means it does not have electrical charge and it is responsible for approximately half of the mass of the atom, given that its mass is almost the same of the proton. The mass of a neutron is approximately 1.674 x 10^-27 kg
Room temperature has the highest viscosity
