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.

How many moles of copper (Cu) are in 65.8 g Cu?
Veseljchak [2.6K]
<h2><u>Answer:</u></h2>

The correct answer is A) 1.04 mol Cu

{65.8 g     /   63.55 g/mol}

= 1.04 mol Cu

Explanation:

In  63.55  g  of copper metal there are  1 m o l  of  C u  atoms. By dividing the mass of Cu and molar mass, we can easily get the number of moles.

can someone explain how this is wrong? I don’t think it is wrong but my chem teacher deducted points. so why?

Answer: measure the mass (48.425g) of KCl

Explanation:

To prepare the solution 0.65M KCl we must measure the mass of KCl that would be dissolved in 1L of the solution. This can be achieved by:

Molar Mass of KCl = 39 + 35.5 = 74.5g/mol

Number of mole (n) = 0.65

Mass conc of KCl = n x molar Mass

Mass conc of KCl = 0.65 x 74.5 = 48.425g

Therefore, to make 0.65M KCl, we must measure 48.425g
