Alex

Answer:

D

Explanation:

gravitational force: F=GmM/r^2

so this equation tells you that when mass increases force increases and when the distance increases force decreases

since the mass of the objects is the same in both cases, but distance is greater in case B than case A, case B has a smaller attractive force compared to A

What volume in liters of 5.75×10−2 M KH2AsO4 contains 6.30 g KH2AsO4?
AnnZ [28]

Answer : The volume of solution is, 0.609 L

Explanation : Given,

Mass of KH_2AsO_4 = 6.30 g

Molar mass of KH_2AsO_4 = 180 g/mole

Concentration = 5.75\times 10^{-2}M

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Mass of }KH_2AsO_4}{\text{Molar mass of }KH_2AsO_4\times \text{Volume of solution (in L)}}

Now put all the given values in this formula, we get:

5.75\times 10^{-2}M=\frac{6.30g}{180g/mole\times \text{Volume of solution (in L)}}

\text{Volume of solution (in L)}=0.609L

Therefore, the volume of solution is, 0.609 L
