Answer is: (C)- 637 N.

Gravity as a force which causes any two bodies to be attracted to each other.  

The gravitational effect increases as the size of an object increases. Earth s surrounded by its own gravitational field.

The weight of an object is the amount of force acting on the object due to gravity. SI unit for weight is newton (N).

m(object) = 65 kg.

g = 9.8 m/s²; the acceleration of free fall.

W = m·g.

W = 65 kg · 9.8 m/s².

W = 637 N; weight of the object A.

Which atomic model states that it is impossible to know the exact location of electrons around the nucleus?
Alja [10]
<span>The correct answer is electron-cloud model. This model states that electrons don't go around in an eliptical way but rather completely erratically and uncontrolably and this is why it can't be known where they are or how they will behave. They form sort of like a cloud of many electrons that move erratically so you have to check it to see where it is.</span>

A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4
san4es73 [151]

Answer:

83.20 g of Na3PO4

Explanation:

1 mole of Na3PO4 contains 3 moles of Na+.

Mole of Na ion to be prepared = Molarity x volume

                 = 0.700 x 725/1000

                     = 0.5075 mole

If 1 mole of Na3PO4 contains 3 moles of Na ion, then 0.5075 Na ion will be contained in:

           0.5075/3 x 1 = 0.1692 mole of Na3PO4

mole of Na3PO4 = mass/molar mass = 0.1692

Hence, mass of Na3PO4 = 0.1692 x molar mass

                                     = 0.1692 x 163.94

                                        = 83.20 g.

83.20 g of Na3PO4 will be needed.
