Answer:
2.67 M
Explanation:
Molarity, which is the molar concentration of a substance, can be calculated using the formula;
M = n/V
Where;
M = molarity (M)
n = number of moles (mol)
V = volume (Litres)
Based on the provided information in this question, mass of lithium sulfate (Li2SO4) = 734g, volume = 2.5L
Using mole = mass/molar mass
Molar mass of Li2SO4 = 7(2) + 32 + 16(4)
= 14 + 32 + 64
= 110g/mol
Mole = 734/110
Mole (n) = 6.67moles
Molarity = n/V
Molarity = 6.67/2.5
Molarity = 2.668
Molarity of Li2SO4 in the solution is 2.67 M
Pluto's orbit is within the Kuiper Belt and has a special relationship to Neptune's orbit.
The correct option is B.
Insulating the attic and the walls will regulates the rate at which the house absorb heat from the heater and at the same time it will regulates the rate at which the heat is lost when the heater is not on. Thus, installing an insulator will help improve the heating and the cooling of the house.
The arrow doesn’t “point” to anything really, it means that the reactants form (or change) into the products.
