Answer: weight , mass

Explanation:

Mass is defined as the amount of matter contained in a body. It is measured in units of kg, g and mg.

Weight of an object is the force acting on an object by virtue of its mass.

weight=m\times g

m =  mass

g = acceleration due to gravity

As the value of g keeps changing from earth to space, the weight of the person would also keep changing. The mass of the person will remain same .

A mechanic needs a radiator to have 50% antifreeze solution. the radiator currently is filled with 4 gallons of 15% antifreeze s
Zanzabum

<span>let x=gallons of current mixture to be drained and replaced with pure antifreeze.
4-x=gallons of current mixture remaining in the car.</span>

<span>
0.15(4-x)+1.00x=0.50 x 4
0.6-.15x+x=2
0.85x=1.4
x=1.4/0.85 =1.65 gal

Thus, 1.65 gallons of current mixture to be drained and replaced with pure antifreeze.</span>

What is the molarity of a solution if you take 12.0 grams of ca(no3)2 and mix it with 0.105 l of water?
Lunna [17]
The  molarity  of  a solution  if it tale 12.0   grams  of  Ca(No3)2  is  calculated as below

molarity =  moles/volume in liters
 moles = mass/molar mass =  12.0 g/ 164 g/mol =  0.073 moles

molarity is therefore  = 0.073/0.105 = 0.7 M
